New Clues to Jet Launching: The inner disks in radio loud quasars may be more stable
Zhen-Yi Cai, Yu-Han Sun, Jun-Xian Wang +3
Jet launching in radio loud (RL) quasars is one of the fundamental problems in astrophysics. Exploring the differences in the inner accretion disk properties between RL and radio q…
Overdensity of submillimeter galaxies around the MAMMOTH-1 nebula
F. Arrigoni Battaia, Chian-Chou Chen, M. Fumagalli +7
In the hierarchical model of structure formation, giant elliptical galaxies form through merging processes within the highest density peaks known as protoclusters. While high-redsh…
An intrinsic link between long-term UV/optical variations and X-ray loudness in quasars
Wen-yong Kang, Jun-Xian Wang, Zhen-Yi Cai +5
Observations have shown that UV/optical variation amplitude of quasars depend on several physi- cal parameters including luminosity, Eddington ratio, and likely also black hole mas…
MAHALO Deep Cluster Survey II. Characterizing massive forming galaxies in the Spiderweb protocluster at z=2.2
Rhythm Shimakawa, Yusei Koyama, Huub J. A. Rottgering +10
This paper is the second in a series presenting the results of our deep H-line survey towards protoclusters at , based on narrow-band imaging with the Subaru Telescope. Thi…
Dust in galaxy clusters: Modeling at millimeter wavelengths and impact on Planck cluster cosmology
J. -B. Melin, J. G. Bartlett, Z. -Y. Cai +4
We have examined dust emission in galaxy clusters at millimeter wavelengths using the Planck map to constrain the model based on Herschel observations that was u…
Direct evidence of AGN-feedback: a post starburst galaxy stripped of its gas by AGN-driven winds
Dalya Baron, Hagai Netzer, J. Xavier Prochaska +7
Post starburst E+A galaxies show indications of a powerful starburst that was quenched abruptly. Their disturbed, bulge-dominated morphologies suggest that they are merger remnants…
Keck/Palomar Cosmic Web Imagers (KCWI/PCWI) Reveal an Enormous Ly Nebula in an Extremely Overdense QSO Pair Field at
Zheng Cai, Erika Hamden, Matt Matuszewski +10
Enormous Ly nebulae (ELANe) represent the extrema of Ly nebulosities. They have detected extents of kpc in Ly and Ly luminosities erg s. The EL…
Star formation across cosmic time with radio surveys. The promise of the SKA
Gianfranco De Zotti, Matteo Bonato, Zhen-Yi Cai
This lecture briefly reviews the major recent advances in radio astronomy made possible by ultra-deep surveys, reaching microJansky flux density levels. A giant step forward in man…
