On the Mass Loading of AGN-Driven Outflows in Elliptical Galaxies and Clusters

no code implementations11 Mar 2021 Yu Qiu, Brian R. McNamara, Tamara Bogdanovic, Kohei Inayoshi, Luis C. Ho

In this work, we use a single parameter, outflow-to-accretion mass-loading factor $m=\dot{M}_{\rm out}/\dot{M}_{\rm BH}$, to characterize the outflows that mediate the interaction between SMBHs and their hosts.

The Infrared Emission and Vigorous Star Formation of Low-redshift Quasars

no code implementations4 Feb 2021 Yanxia Xie, Luis C. Ho, Ming-Yang Zhuang, Jinyi Shangguan

The star formation activity of the host galaxies of active galactic nuclei (AGNs) provides valuable insights into the complex interconnections between black hole growth and galaxy evolution.

The Evolutionary Pathways of Disk-, Bulge-, and Halo-dominated Galaxies

no code implementations29 Jan 2021 Min Du, Luis C. Ho, Victor P. Debattista, Annalisa Pillepich, Dylan Nelson, Lars Hernquist, Rainer Weinberger

In observations, both bulge- and halo-dominated galaxies are likely to be classified as early-type galaxies with compact morphology and quiescent star formation.

From haloes to galaxies -- II. The fundamental relations in star formation and quenching

no code implementations7 Oct 2020 Jing Dou, Yingjie Peng, Alvio Renzini, Luis C. Ho, Filippo Mannucci, Emanuele Daddi, Yu Gao, Roberto Maiolino, Chengpeng Zhang, Qiusheng Gu, Di Li, Simon J. Lilly, Feng Yuan

We show the integrated $M_{\rm H_2}$-SFR, SFR-$M_*$ and $M_{\rm H_2}$-$M_*$ relation can be simply transformed from the $\mu$-sSFR, SFE-$\mu$ and SFE-sSFR relation, respectively.

Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. VIII. Structure of the Broad-Line Region and Mass of the Central Black Hole in Mrk 142

no code implementations15 Nov 2018 Yan-Rong Li, Yu-Yang Songsheng, Jie Qiu, Chen Hu, Pu Du, Kai-Xing Lu, Ying-Ke Huang, Jin-Ming Bai, Wei-Hao Bian, Ye-Fei Yuan, Luis C. Ho, Jian-Min Wang

We apply three BLR models with different prescriptions of BLR clouds distributions and find that the best model for fitting the data of Mrk 142 is a two-zone BLR model, consistent with the theoretical BLR model surrounding slim accretion disks.

Estimating Black Hole Masses in Active Galaxies Using the Halpha Emission Line

1 code implementation15 Aug 2005 Jenny E. Greene, Luis C. Ho

It has been established that virial masses for black holes in low-redshift active galaxies can be estimated from measurements of the optical continuum strength and the width of the broad Hbeta line.
