We present an overview of the near-InfraRed Multi-Object Spectrograph (IRMOS) for the Thirty Meter Telescope, as developed under a Feasibility Study at the University of Florida and Herzberg Institute of Astrophysics. IRMOS incorporates a multi-object adaptive optics correction capability over a 5-arcminute field of regard on TMT. Up to 20

Dwarf galaxies are the most common galaxies in the Universe. They are systems believed to consist of matter in a near-primordial state, from which giant galaxies probably form. As such, they are important probes for studying matter in its near-primordial state. In an effort to study the main physical and chemical properties of dwarfs, the present

We study the density profiles of collapsed galaxy-size dark matter halos with masses 1011 to 5×1012 Msolar focusing mostly on the halo outer regions from the formal virial radius Rvir up to 5Rvir-7Rvir. We find that isolated halos in this mass range extend well beyond Rvir exhibiting all properties of virialized objects up to 2Rvir-3Rvir

SPIRE, the Spectral and Photometric Imaging Receiver, is a submillimetre camera and spectrometer for the European Space Agency's Herschel Space Observatory. It comprises a three-band imaging photometer operating at 250, 360 and 520 μm, and an imaging Fourier Transform Spectrometer (FTS) covering 200-670 μm. The detectors are arrays of feedhorn

The Gran Telescopio Canarias (GTC) 10.4m telescope will be having its first light soon after this meeting. A fairly complete set of science instruments are being prepared for installation at the GTC soon after first light or a couple of year after in the case of the second generation instruments. In this talk I will describe the main features of
