Journal ArticleDOI
The Mass of the Black Hole in Arp 151 from Bayesian Modeling of Reverberation Mapping Data
Brendon J. Brewer,Tommaso Treu,Anna Pancoast,Aaron J. Barth,Vardha N. Bennert,Misty C. Bentz,Alexei V. Filippenko,Jenny E. Greene,Matthew A. Malkan,Jong-Hak Woo +9 more
TL;DR: In this paper, the mass of a supermassive black hole in an active galactic nucleus (Arp 151) was estimated based on the motion of the gas responsible for the broad emission lines.
Journal ArticleDOI
Probing sub-galactic mass structure with the power spectrum of surface-brightness anomalies in high-resolution observations of galaxy-galaxy strong gravitational lenses. I. Power-spectrum measurement and feasibility study
Dorota Bayer,Léon V. E. Koopmans,John McKean,Simona Vegetti,Tommaso Treu,Christopher D. Fassnacht,Karl Glazebrook +6 more
TL;DR: In this paper , the authors measured the power spectrum of surface-brightness anomalies from high-resolution Hubble Space Telescope (HST) imaging and compared the measured power spectrum to the statistical properties of the underlying small-scale mass structures in the lens galaxy and infer the first observational constraints on the sub-galactic matter power spectrum in a massive elliptical galaxy.
Journal ArticleDOI
Early Results from GLASS-JWST. XX. Unveiling a Population of “Red Excess” Galaxies in Abell2744 and in the Coeval Field
Benedetta Vulcani,Tommaso Treu,A. Calabrò,Jacopo Fritz,Bianca M. Poggianti,P. Bergamini,Andrea Bonchi,K. Boyett,G. B. Caminha,Marco Castellano,Alan Dressler,Adriano Fontana,Karl Glazebrook,Claudio Grillo,Matthew A. Malkan,Sara Mascia,Amata Mercurio,Emiliano Merlin,Benjamin Metha,Takahiro Morishita,Themiya Nanayakkara,Diego Paris,Guido Roberts-Borsani,Piero Rosati,Namrata Roy,Paola Santini,Michele Trenti,Eros Vanzella,Xin Wang +28 more
TL;DR: In this paper , the authors combine JWST/NIRCam imaging and MUSE data to characterize the properties of galaxies in different environmental conditions in the cluster Abell2744 and in its immediate surroundings.
Journal ArticleDOI
Understanding the Unique Assembly History of Central Group Galaxies
Benedetta Vulcani,Kevin Bundy,Claire Lackner,Alexie Leauthaud,Tommaso Treu,Simona Mei,Lodovico Coccato,Jean-Paul Kneib,Matthew W. Auger,Carlo Nipoti +9 more
TL;DR: In this paper, the authors compare the scaling relations of early-type central galaxies and non-CGs at z~0.6 and find that even group-scale central galaxies can develop extended components by these redshifts that can increase total $R_e$ and M_star estimates by a factor of 2.
Journal ArticleDOI
The Fundamental Plane of Bulges at Intermediate Redshift
TL;DR: In this paper, the diversity and evolutionary properties of distant galactic bulges in the context of well-established trends for pure spheroidal galaxies were investigated and isolated for a sample of 137 spiral galaxies in the GOODS fields within the redshift range 0.1 0.2.
