We present the completion of a program to cross-correlate the SDSS Data Release 1 and 2MASS Point Source Catalog in search for extremely red L and T dwarfs. The...

The success of the next generation of instruments for 8 to 40-m class telescopes will depend on the ability of Adaptive Optics (AO) systems to provide excellent...

Thick discs are disc-like components with a scale height larger than that of the classical discs. They are most easily detected in close to edge-on galaxies in...

Transmission spectroscopy has been a powerful tool to decipher the atmospheric compositions of transiting exoplanets. The recent HST survey has shown that...

A discussion of the first observation ever of gravitational waves. Present detectors, future detectors, and the perspectives for gravitational wave astronomy.

In the next decade astronomers will attempt to constrain the nature of dark matter, dark energy and the (perhaps inflationary) processes which generated...

I will present new deep and wide narrow-band surveys undertaken with UKIRT, Subaru and the VLT; a unique combined effort to select large, robust samples of H...

In this talk, I will review some highlights of my studies of star formation in the past 35 years. I started my PhD thesis on the theory of the stellar IMF in...

Using ~320h of good-quality Crab data from Feb 2007 to Apr 2014 the MAGIC telescopes measured the most energetic pulsed photons from a pulsar to date. The new...
