H I Properties of Field Galaxies at -0.6: Insights into Declining Cosmic Star Formation
David DePalma, Neeraj Gupta, Hsiao-Wen Chen +18
We report statistically significant detection of H I 21-cm emission from intermediate-redshift (-0.6) galaxies. By leveraging multi-sightline galaxy survey data from t…
MUSEQuBES: Physical conditions, origins, and multi-element abundances of the circumgalactic medium of an isolated, star-forming dwarf galaxy at z=0.57
Sean D. Johnson, Nishant Mishra, Sowgat Muzahid +13
In dwarf galaxy models, outflows expel metal-enriched interstellar medium (ISM) into the circumgalactic medium (CGM) to reproduce their observed low metallicities, but measurements…
Probing the \ion{He}{2} re-Ionization ERa via Absorbing \ion{C}{4} Historical Yield (HIERACHY) IV: A complex redshifted absorption system intrinsic to quasar
Huiyang Mao, Jiang-Tao Li, Xiaodi Yu +3
High-resolution spectra provide a powerful tool in studying the associated absorption lines (AALs) in quasars. We present a case study of the quasar J014741-030247 at 4.75…
Probing the He II reionization ERa via Absorbing C IV Historical Yield (HIERACHY) III: The C IV absorber catalog and initial results on cosmic abundance evolution at
Xiaodi Yu, Zhijie Qu, Zheng Cai +3
As part of the HIERACHY program, we collect the high-SN and high-spectral resolution optical spectra of 25 quasars at to constrain the C IV evolution at $z\approx 3-5…
The Morphology and Kinematics of a Giant, Symmetric Nebula Around a Radio-Loud Quasar 3C57: Extended Rotating Gas or Biconical Outflows?
Zhuoqi, Liu, Sean D. Johnson +12
Gas flows between galaxies and the CGM play a crucial role in galaxy evolution. When ionized by a quasar, these gas flows can be directly traced as giant nebulae. We present a stud…
Probing the He II re-Ionization ERa via Absorbing C IV Historical Yield (HIERACHY) II: Project Design, Current Status, and Examples of Initial Data Products
Jiang-Tao Li, Xiaodi Yu, Huiyang Mao +22
The He II reionization epoch is expected to take place at . In this stage, the helium and metals in the inter-galactic medium (IGM) are further ionized with additional co…
