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…
Witnessing the Formation of a Brightest Cluster Galaxy in a Nearby X-ray Cluster
Jesper Rasmussen, John S. Mulchaey, Lei Bai +3
The central dominant galaxies in galaxy clusters constitute the most massive and luminous galaxies in the Universe. Despite this, the formation of these brightest cluster galaxies…
The First Mid-IR View of the Star-forming Properties of Nearby Galaxy Groups
Lei Bai, Jesper Rasmussen, John S. Mulchaey +3
We present the first mid-IR study of galaxy groups in the nearby Universe based on Spitzer MIPS observations of a sample of nine redshift-selected groups from the XMM-IMACS (XI) pr…
