Submillimeter-selected Galaxies
The first generation of submillimeter(submm)-wave surveys are being carried out using the 450/850-μm SCUBA camera at the JCMT on Mauna Kea. These surveys are potentially sensitive to galaxies at very high redshift, and the galaxies that have been detected so far appear to contribute the greater fraction of the mm/submm-wave background radiation intensity measured by COBE. In order to understand...
متن کاملClustering of Submillimeter - Selected Galaxies
Using accurate positions from very deep radio observations to guide multi-object Keck spectroscopy, we have determined a substantially complete redshift distribution for very luminous, distant submillimeter(submm)-selected galaxies (SMGs). A sample of 73 redshifts for SMGs in 7 fields contains a surprisingly large number of ‘associations’: systems of SMGs with Mpc-scale separations, and redshif...
متن کاملNear-infrared Colors of Submillimeter-selected Galaxies
We report on deep near-infrared (NIR) observations of submillimeter-selected galaxies (SMGs) with the Near Infrared Camera (NIRC) on the Keck I telescope. We have identified K-band candidate counterparts for 12 out of 15 sources in the SCUBA Cluster Lens Survey. Three SMGs remain nondetections with K-band limits of K > 23mag, corrected for lensing. Compensating for lensing we find a median magn...
متن کاملStellar Populations in the Central Galaxies of Fossil Groups
It is inferred from the symmetrical and luminous X-ray emission of fossil groups that they are mature, relaxed galaxy systems. Cosmological simulations and observations focusing on their dark halo and inter-galactic medium properties confirm their early formation. Recent photometric observations suggest that, unlike the majority of non-fossil brightest group galaxies (BGGs), the central early-t...
متن کاملThe Relationship between Stellar and Black-hole Mass in Submillimeter Galaxies
We analyze deep X-ray, optical and mid-infrared Spitzer observations of the CDF-N/GOODS-N region to study a sample of 13 submillimeter-detected galaxies with spectroscopic redshifts (median z = 2.2). These galaxies are among the most active and massive at this epoch. We find evidence for a power-law correlation between the estimated stellar and X-ray luminosity, implying that masses of the blac...
