Abstract

 

SOFIA, short for Stratospheric Observatory for Infrared Astronomy,
is a 2.7m telescope flying on a Boeing 747SP at altitudes of 12-14km,
to detect and study mid- and far-infrared radiation that is blocked
by water vapor in the earth's atmosphere and cannot reach the
ground. It is the successor to the Kuiper Airborne Observatory (1974-1995)
and currently the only access to and platform for astronomical observations
in the far-infrared (30-300 microns), except for balloon-borne telescopes.
 
SOFIA normally flies out of California, but once a year also
deploys to the Southern Hemisphere (usually to Christchurch,
New Zealand), benefitting from the excellent wintertime
stratospheric conditions to study the rich southern skies.
Although a bilateral project (80:20)
between USA (NASA/USRA) and Germany (DLR/DSI), it is open for
proposals from the world-wide astronomical community at large.
It addresses many science questions that ESA's successful but
now extinct Herschel Observatory has left unanswered and
offers observational opportunities similar to and beyond Herschel.
SOFIA also has many synergies with ALMA and APEX, as well as IRAM
and other submm and radio telescopes.

In part I of this SOFIA lecture, I will introduce the observatory 
in general, the plane, the telescope, the mode of operation, and 
in particular the current and future instrumentation.

In part II (later this week),  I will present a glimpse of SOFIA science
highlights and discoveries in its first 6 years of operation
(since 2012), including the most recent astrophysical and astrochemical 
results. I will also address its future ISM and star formation potential.  

SOFIA is a unique observatory, different from ground-based and
space platforms, which will serve the mid- and far-infrared 
astronomical community for many years to come.
 
It is a fascinating experience to fly on SOFIA!

Abstract

Tigre is a 1.2m f:8 RC robotic telescope designed to do spectroscopic monitoring of dynamical processes, mainly in stellar astrophysics, for objects of less than 2" of size and brighter than magnitude 10...11. Its 2-channel (red/blue) echelle spectrograph HEROS has a resolution of 20,000 and covers simultaneously almost the whole range from the near IR to near UV (8800-3800A). It can also be used to determine the exact physical properties of stellar samples of interest, comparing high s/n (80-120) spectra with PHOENIX models and iSpec analysis. The large amount of spectroscopic data ideally serves a large variety of undergraduate and graduate thesis projects. This presentation gives a brief insight into this dedicated, yet economic international project of the universities of Hamburg, Guanajuato and Liege and the opportunities it has to offer to the international community.

Embry-Riddle Aeronautical University

Abstract

For over 20 years, the Southeastern Association for Research in Astronomy (SARA) has operated a remotely-accessible 1-m-class telescope at the Kitt Peak National Observatory near Tucson, Arizona that has served as a focus for faculty and student research.  From its four charter institutional members, the SARA consortium has grown to include a dozen universities spanning Indiana to Florida.  In 2007, SARA assumed operations of a similar remotely-operated telescope at Cerro Tololo Interamerican Observatory in Chile.  SARA has most recently partnered with the Instituto de Astrofisica de Canarias (IAC) to automate and assume operations of the Jacobus Kapteyn Telescope (JKT) at the Roque des los Muchachos on La Palma.  This talk will provide a brief historical perspective on the SARA consortium as well as a summary of our facilities, research interests and prospects for the future.

Astrophysics Research Institute (Univ. John Moores Liverpoool)

Abstract

The Astrophysics Research Institute (ARI) was established at LJMU in 1992. Today the Institute comprises around 70 staff and research students working on topics ranging from stellar evolution to cosmology. In this talk I will give an overview and some highlights of the work undertaken in recent years on Classical and Recurrent novae by the nova group of the ARI. This involves multi-frequency observations of both Galactic novae and those in Local Group galaxies and includes topics such as the exploration of their potential links to the progenitors of Type Ia supernovae. Along the way, I will briefly describe the work of the Liverpool Telescope on La Palma, one of whose primary science drivers is the efficient and effective observation of transient objects such as these, and look forward to our plans for the development of an even larger and faster-reacting robotic telescope at ORM - currently codenamed 'LT2".

ESO

Abstract

ESO is an intergovernmental organization for astronomy founded in 1962 by five countries. It currently has 14 Member States in Europe with Brazil poised to join as soon as the Accession Agreement has been ratified. Together these countries represent approximately 30 percent of the world’s astronomers. ESO operates optical/infrared observatories on La Silla and Paranal in Chile, partners in the sub-millimeter radio observatories APEX and ALMA on Chajnantor and is about to start construction of the Extremely Large Telescope on Armazones.

La Silla hosts various robotic telescopes and experiments as well as the NTT and the venerable 3.6m telescope. The former had a key role in the discovery of the accelerating expansion of the Universe and the latter hosts the ultra-stable spectrograph HARPS which is responsible for the discovery of nearly two-thirds of all confirmed exoplanets with masses below that of Neptune. On Paranal the four 8.2m units of the Very Large Telescope, the Interferometer and the survey telescopes VISTA and VST together constitute an integrated system which supports 16 powerful facility instruments, including adaptive-optics-assisted imagers and integral-field spectrographs, with half a dozen more on the way and the Extremely Large Telescope with its suite of instruments to be added to this system in about ten years time. Scientific highlights include the characterisation of the supermassive black hole in the Galactic Centre, the first image of an exoplanet, studies of gamma-ray bursts enabled by the Rapid Response Mode and milliarcsec imaging of evolved stars and active galactic nuclei. The single dish APEX antenna, equipped with spectrometers and wide-field cameras, contributes strongly to the study of high-redshift galaxies and of star- and planet-formation. Early Science results obtained with the ALMA interferometer already demonstrate its tremendous potential for observations of the cold Universe.

Abstract

The robotic 2m Liverpool Telescope, based on La Palma, is owned and
operated by Liverpool John Moores University. It has a diverse
instrument suite and a strong track record in time domain science,
with highlights including early time photometry and spectra of
supernovae, measurements of the polarization of gamma-ray burst
afterglows, and high cadence light curves of transiting extrasolar
planets. In the next decade the time domain will become an
increasingly prominent part of the astronomical agenda with the
arrival of new facilities such as LSST, SKA, CTA, Gaia and the next
generation of exoplanet finders. Additionally, detections of
astrophysical gravitational wave and neutrino sources opening new
windows on the transient universe. To capitalise on this exciting new
era we intend to build Liverpool Telescope 2: a new robotic facility
on La Palma dedicated to time domain science. The next generation of
survey facilities will discover large numbers of variable and
transient objects, but there will be a pressing need for follow-up
observations for scientific exploitation, in particular spectroscopic
follow-up. Liverpool Telescope 2 will have a 4 metre aperture,
enabling optical/infrared spectroscopy of faint objects. Robotic
telescopes are capable of rapid reaction to unpredictable phenomena,
and for fast-fading transients like gamma-ray burst afterglows, this
rapid reaction enables observations which would be impossible on less
agile telescopes of much larger aperture. We intend Liverpool
Telescope 2 to have a world-leading response time, with the aim that
we will be taking data with a few tens of seconds of receipt of a
trigger from a ground- or space-based transient detection facility. In
this talk I will discuss the role for Liverpool Telescope 2 in the
2020+ astronomical landscape, the key science topics we hope to
address, and the results of our preliminary optical design studies.

Abstract

Golden Age of Astronomy” does not only influence professional but also amateur astronomy. Today, amateurs basically use the same technologies as the professionals. This includes the most important tool – spectroscopy. There is an important gap in professional astronomical spectroscopy which can be filled by amateurs and their smaller telescopes. Some stellar phenomena need longer time coverage, of order, e.g., some weeks. This is especially valid for binary stars. One such interesting target is Wolf-Rayet 140, a WR+O binary with a highly eccentric orbit and a period of about 8 years. The observation of its periastron passage in the visible wavelength range is valuable for measurements in other wavelength domains to understand the wind-wind shock interaction of both components and the global geometry and physics of the system. For this and some other massive star targets, a group of amateur and professional astronomers performed a successful campaign for 116 nights at the 50 cm Mons telescope at Teide observatory, supported by the IAC and embedded in a joint worldwide X-ray, visual and IR campaign. The group of observers was a mix of enthusiastic astronomers from various professions (e.g., physicists, a physics student, a chemist, a physician, a schoolboy, a pilot) but they all have been experienced and enthusiastic observers. The talk will highlight the most important results of this campaign

Abstract

Teams from industry, universities and institutes across Europe are contributing to the design and development phase of the European Southern Observatory's project to build the world's biggest optical/infrared telescope. I will outline some of exciting scientific prospects for a fully-adaptive 42m telescope, from studying exoplanets to the furthest galaxies, and then show how some of the technical challenges are being addressed. I will place special emphasis on the work UK teams are doing on instrumentation, detectors and adaptive optics.

Abstract

The main goal of the MASTER-Net project is to produce a unique fast sky survey with all sky observed over a single night down to a limiting magnitude of 21. Such a survey will make it possible to address a number of fundamental problems: search for dark energy via the discovery and photometry of supernovae (including SNIa), search for exoplanets, microlensing effects, discovery of minor bodies in the Solar System, and space-junk monitoring. All MASTER telescopes can be guided by alerts, and we plan to observe prompt optical emission from gamma-ray bursts synchronously in several filters and in several polarization planes.
