Gravitational lensing reveals cool gas within 10-20 kpc around a quiescent galaxy

Communications Physics
While quiescent galaxies have comparable amounts of cool gas in their outer circumgalactic medium (CGM) compared to star-forming galaxies, they have significantly less interstellar gas.

Star Formation under a Cosmic Microscope: Highly Magnified z = 11 Galaxy behind the Bullet Cluster

The Astrophysical Journal Letters
We present measurements of stellar population properties of a newly discovered, spectroscopically confirmed, $z=11.1{0}_{-0.26}^{+0.11}$ , gravitationally lensed galaxy, using JWST NIRSpec PRISM spectroscopy and NIRCam imaging.

Multiwavelength perspective of AGN evolution

, 2010
Discovering and studying obscured AGN at z>1-3 is important not only to complete the AGN census, but also because they can pinpoint galaxies where nuclear accretion and star-formation are coeval, and mark the onset of AGN feedback.

Scalable N-body code for the modelling of early-type galaxies

, 2007
Early-type galaxies exhibit a wealth of photometric and dynamical structures. These signatures are fossil records of their formation and evolution processes.

An Imaging and Spectroscopic Exploration of the Dusty Compact Obscured Nucleus Galaxy Zw 049.057

The Astrophysical Journal Supplement Series
Zw 049.057 is a moderate-mass, dusty, early-type galaxy that hosts a powerful compact obscured nucleus (CON, L _FIR,CON ≥ 10 ^11 L _⊙ ). The resolution of the Hubble Space Telescope enabled measurements of the stellar light distribution and ...

Deciphering Gas Dynamics and Star Formation in a z = 1.1 Main-sequence Spiral Galaxy with ALMA and JWST

The Astrophysical Journal
We present a joint analysis of high-resolution CO(2–1) and Paschen- α (Pa α ) emission lines to trace gas dynamics and spatially resolved star formation in ASPECS-LP.3 mm.06, a z = 1.1 main-sequence galaxy.
