Luminous Satellites II: Spatial Distribution, Luminosity Function and Cosmic Evolution
Anna Nierenberg,Matthew W. Auger,Tommaso Treu,Philip J. Marshall,Christopher D. Fassnacht,Michael T. Busha,Michael T. Busha +6 more
TL;DR: In this article, the authors infer the normalization and the radial and angular distributions of the number density of satellites of massive galaxies in the COSMOS HST images and detect satellites up to eight magnitudes fainter than the host galaxies and as close as 0.3 (1.4) arcseconds (kpc).
Environmental Effects in the Evolution of Galactic Bulges
TL;DR: In this paper, the authors investigate possible environmental trends in the evolution of galactic bulges over the redshift range 0 = 0.4 and =0.54 using surface photometry based on HST imaging and velocity dispersions based on Keck spectroscopy.
JWST Lensed quasar dark matter survey II: Strongest gravitational lensing limit on the dark matter free streaming length to date
Ryan E. Keeley,Anna Nierenberg,Daniel Gilman,Charles Gannon,Simon Birrer,Tommaso Treu,A. J. Benson,X. Du,Kevork N. Abazajian,T. Anguita,Vardha N. Bennert,S. G. Djorgovski,K. K. Gupta,Sebastian F. Hoenig,Alexander Kusenko,C. Lemon,M. Malkan,V. Motta,L. Moustakas,M. S. H. Oh,Dominique Sluse,D. Stern,R. H. Wechsler +22 more
TL;DR: Researchers use JWST to constrain dark matter properties by measuring warm dust emission in 9 multiply imaged quasars, yielding a 10:1 odds upper limit on the half-mode mass of 107.6M⊙, corresponding to a 6.1 keV dark matter particle mass.
Overdensities of Y-dropout Galaxies from the Brightest-of-Reionizing Galaxies Survey: A Candidate Protocluster at Redshift z ≈ 8
Michele Trenti,Larry Bradley,Massimo Stiavelli,J. M. Shull,Pascal Oesch,Rychard Bouwens,Rychard Bouwens,Joseph A. Muñoz,Emilio Romano-Diaz,Tommaso Treu,Isaac Shlosman,C. M. Carollo +11 more
TL;DR: In this paper, the authors extended the search for Y098-dropout sources to fainter luminosities (M∗ galaxies with MAB ∼ −20), with detections at > 5� confidence (compared to the 8� confidence threshold adopted earlier).
Scaling relations between black holes and their host galaxies: comparing theoretical and observational measurements, and the impact of selection effects
Colin DeGraf,Colin DeGraf,T. Di Matteo,Tommaso Treu,Tommaso Treu,Yu Feng,Jong-Hak Woo,Daeseong Park +7 more
TL;DR: In this article, the scaling relations between black hole mass and host galaxy properties (sigma, M*, and LV) were examined in the high-resolution simulation MassiveBlackII.
