On the nature of the unusual transient AT 2018cow from HI observations of its host galaxy
Michał J. Michałowski, P. Kamphuis, J. Hjorth +23
Unusual stellar explosions represent an opportunity to learn about both stellar and galaxy evolution. Mapping the atomic gas in host galaxies of such transients can lead to an unde…
SImulator of GAlaxy Millimetre/submillimetre Emission (SIGAME): CO emission from massive z=2 main-sequence galaxies
Karen P. Olsen, Thomas R. Greve, Christian Brinch +4
We present SIGAME (SImulator of GAlaxy Millimetre/submillimetre Emission), a new numerical code designed to simulate the 12CO rotational line emission spectrum of galaxies. Using s…
Measuring the total and baryonic mass profiles of the very massive CASSOWARY 31 strong lens. A fossil system at z ~ 0.7?
C. Grillo, L. Christensen, A. Gallazzi +1
We investigate the total and baryonic mass distributions in deflector number 31 of the Cambridge And Sloan Survey Of Wide ARcs in the skY (CASSOWARY). We confirm spectroscopically…
Evidence for Widespread AGN Activity among Massive Quiescent Galaxies at z ~ 2
Karen Pardos Olsen, Jesper Rasmussen, Sune Toft +1
We quantify the presence of Active Galactic nuclei (AGN) in a mass-complete (M_* >5e10 M_sun) sample of 123 star-forming and quiescent galaxies at 1.5 < z < 2.5, using X-ray data f…
The Suppression of Star Formation and the Effect of Galaxy Environment in Low-Redshift Galaxy Groups
Jesper Rasmussen, John S. Mulchaey, Lei Bai +3
Understanding the interaction between galaxies and their surroundings is central to building a coherent picture of galaxy evolution. Here we use GALEX imaging of a statistically re…
Hot and Cold Galactic Gas in the NGC 2563 Galaxy Group
Jesper Rasmussen, Xue-Ning Bai, John S. Mulchaey +7
The role of environmentally induced gas stripping in driving galaxy evolution in groups remains poorly understood. Here we present extensive Chandra and Very Large Array mosaic obs…
