Stars and dark matter in the spiral gravitational lens 2237+0305
TL;DR: In this paper, a mass model for the spiral lens galaxy 2237+0305, at redshift z_l=0.04, based on gravitational-lensing constraints, HI rotation, and new stellar-kinematic information, was obtained by fitting the Mgb-Fe absorption line region.
Journal ArticleDOI
Early Results from GLASS-JWST. XV. Properties of the Faintest Red Sources in the NIRCAM Deep Fields

Paris,Michele Trenti,Tommaso Treu,Paola Santini,X. Wang,K. Boyett,Marusa Bradac,Gabriel B. Brammer,Timothy Jones,Danilo Marchesini,Mario Nonino,Benedetta Vulcani +22 more
TL;DR: In this article , the authors presented a first look at the reddest 2-5 μm sources found in deep images from the GLASS Early Release Science program, i.e., sources detected only in bands redder than is reachable with the Hubble Space Telescope and which would likely not have been identified in pre-JWST surveys.
Journal ArticleDOI
Direct Observation of Cosmic Strings via their Strong Gravitational Lensing Effect: II. Results from the HST/ACS Image Archive
Eric Morganson,Phil Marshall,Phil Marshall,Tommaso Treu,Tim Schrabback,Tim Schrabback,Roger Blandford +6 more
TL;DR: In this paper, the authors search 4.5 square degrees of archival HST/ACS images for cosmic strings, identifying close pairs of similar, faint galaxies and selecting groups whose alignment is consistent with gravitational lensing by a long, straight string.

The Formation of Early-Type Galaxies: Observations to z=1
TL;DR: In this paper, the authors review the observational evidence on these issues, focusing on the redshift range z=0.1-1, and compare it to the predictions of current models of galaxy formation.
Journal ArticleDOI
