Abstract
Simons Observatory (SO) is a new Cosmic Microwave Background telescope currently under construction in the Atacama Desert, close to ALMA and other recent CMB telescopes. It will have six small aperture (42cm) telescopes (SATs), and one large aperture (6m) telescope (LAT), observing at 30-280GHz (1-10mm) using transition edge sensors (TES) and kinetic inductance detectors (KIDs). As well as observing the polarisation of the CMB to unprecedented sensitivity, the LAT will perform a constant survey at higher angular resolution, enabling the systematic detection of transient sources in the submm, with large overlap of optical surveys such as LSST, DESI and DES. As well as giving an overview of SO, I summarise the types of transient sources that are expected to be seen by SO, including flaring stars, quasars, asteroids, and man-made satellites.
Abstract
The SONG SONG (Stellar Observations Network Group) project is a worldwide initiative to design and build a global network of 1m telescopes (6 to 8 nodes) to allow observations with a high duty cycle (> 80%) and near continuous coverage over long time spans (weeks to months). The SONG prototype (first node of the network) is currently under construction and it is expected to be placed at the Observatorio del Teide in mid 2011 on the basis of a bilateral collaborative agreement. The main scientific goals for SONG are to study stars using asteroseismology, and to search for, and characterize, extra-solar planets using microlensing and radial-velocity observations. In order to achieve this, the prototype node will be equipped with a high-resolution spectrograph and a dual-colour lucky-imaging camera. Here we describe the main aspects of the project and the various scientific opportunities that will be offered to the Spanish community.« Newer Older »
