The bending of the star-forming main sequence traces the cold- to hot-accretion transition mass over 0<z<4
E. Daddi, I. Delvecchio, P. Dimauro +8
We analyse measurements of the evolving stellar mass (M0) at which the bending of the star-forming main sequence (MS) occurs over 0<z<4. We find M0~10^10Msun over 0<z<1, then M0 ri…
The Merger Dynamics of the Galaxy Cluster Abell 1775: New Insights from Chandra and XMM-Newton for a Cluster Simultaneously Hosting a WAT and a NAT Radio Sources
Dan Hu, Haiguang Xu, Zhenghao Zhu +13
We present a new study of the merger dynamics of Abell~1775 by analyzing the high-quality Chandra and XMM-Newton archival data. We confirm/identify an arc-shaped edge (i.e., the he…
A deep search for molecular gas in two massive Lyman break galaxies at z=3 and 4: vanishing CO-emission due to low metallicity?
Qinghua Tan, Emanuele Daddi, Mark T. Sargent +14
We present deep IRAM Plateau de Bure Interferometer (PdBI) observations, searching for CO-emission toward two massive, non-lensed Lyman break galaxies (LBGs) at z=3.216 and 4.058.…
The Molecular Gas Content of z = 3 Lyman Break Galaxies; Evidence of a non Evolving Gas Fraction in Main Sequence Galaxies at z > 2
G. E. Magdis, E. Daddi, M. Sargent +10
We present observations of the CO[3-2] emission towards two massive and infrared luminous Lyman Break Galaxies at z = 3.21 and z = 2.92, using the IRAM Plateau de Bure Interferomet…
Molecular Gas in Infrared Ultraluminous QSO Hosts
X. Y. Xia, Y. Gao, C. -N. Hao +6
We report CO detections in 17 out of 19 infrared ultraluminous QSO (IR QSO) hosts observed with the IRAM 30m telescope. The cold molecular gas reservoir in these objects is in a ra…
12CO, 13CO and C18O observations along the major axes of nearby bright infrared galaxies
Qinghua Tan, Yu Gao, Zhiyu Zhang +1
We present simultaneous observations of CO,13CO and C18O J=1-0 emission in 11 nearby (cz<1000 km/s) bright infrared galaxies. Both 12CO and 13CO are detected in the centers of all…
