Extending the Calibration of CIV-Based Single-Epoch Black Hole Mass Estimators for Active Galactic Nuclei
Daeseong Park,Aaron J. Barth,Jong-Hak Woo,Matthew A. Malkan,Tommaso Treu,Vardha N. Bennert,Roberto J. Assef,Anna Pancoast +7 more
TL;DR: In this article, the authors provide an updated calibration of the CIV broad emission line-based single-epoch (SE) black hole (BH) mass estimators for active galactic nuclei (AGNs) using new data for six reverberation-mapped AGNs at redshift $z=0.005-0.234$ with BH masses (bolometric luminosities) in the range $10^{6.5-9.5}-10^{7.9$).
Journal ArticleDOI

Cupani,Adriano Fontana,Roberto Gilli,A. Grazian,Max Gronke,M. Mignoli,Mario Nonino,Laura Pentericci,Paolo Tozzi,Tommaso Treu,Italo Balestra,Mark Dijkstra +23 more
TL;DR: In this article, the MUSE Deep Lensed Field (MDLF) program was used to confirm spectroscopic redshifts for all 136 multiple images of 48 source galaxies at 0.9 10 for individual objects down to de-lensed magnitude 28-30.
Journal ArticleDOI
The Grism Lens-Amplified Survey from Space (GLASS) X. Sub-kpc resolution gas-phase metallicity maps at cosmic noon behind the Hubble Frontier Fields cluster MACS1149.6+2223
Xin Wang,Tucker Jones,Tommaso Treu,Takahiro Morishita,Louis E. Abramson,Gabriel Brammer,Kuang-Han Huang,Matthew A. Malkan,Kasper B. Schmidt,Adriano Fontana,Claudio Grillo,Alaina Henry,W. Karman,Patrick L. Kelly,Charlotte Mason,Amata Mercurio,Piero Rosati,Keren Sharon,Michele Trenti,Benedetta Vulcani +19 more
TL;DR: In this paper, the authors combine deep HST grism spectroscopy with a new Bayesian method to derive maps of gas-phase metallicity, nebular dust extinction, and star-formation rate for 10 star-forming galaxies at high redshift.
Journal ArticleDOI
Stability of the broad-line region geometry and dynamics in Arp 151 over seven years
A. Pancoast,Aaron J. Barth,Keith Horne,Tommaso Treu,Brendon J. Brewer,Vardha N. Bennert,Gabriela Canalizo,Elinor L. Gates,Weidong Li,Matthew A. Malkan,David J. Sand,T. Schmidt,Stefano Valenti,Jong-Hak Woo,Kelsey I. Clubb,Michael C. Cooper,Steven M. Crawford,Sebastian F. Hönig,Michael D. Joner,M. T. Kandrashoff,Mariana S. Lazarova,Anna Nierenberg,Encarni Romero-Colmenero,Donghoon Son,Erik Tollerud,Jonelle L. Walsh,Hartmut Winkler +26 more
TL;DR: In this paper, the authors used a geometric and dynamical model for the broad line region (BLR) of the Seyfert 1 galaxy Arp 151 to constrain the systematic uncertainties in nonvarying parameters such as the black hole mass.
Journal ArticleDOI

Fassnacht,Shude Mao,Steven T. Myers,T. J. Pearson,P. M. Phillips,Anthony C. S. Readhead,David Rusin,Peter N. Wilkinson +19 more
TL;DR: In this article, the authors present observations of the Class B2108+213, the widest separation gravitational lens system discovered by the Cosmic Lens All-Sky Survey, and a plausible mass distribution model for the system is also presented.
