On the Origin of Quenched but Gas-rich Regions at Kiloparsec Scales in Nearby Galaxies

The Astrophysical Journal
We use resolved spectroscopy from MaNGA to investigate the significance of both local and global properties of galaxies to the cessation of star formation at kpc scales.

Spider-webb: Spatially Resolved Evidence of Inside-out Quenching in the Spiderweb Protocluster at z ∼ 2

The Astrophysical Journal
We present a spatially resolved analysis of galaxy quenching within the Spiderweb Protocluster at z  ∼ 2.16, combining deep imaging from the James Webb Space Telescope (JWST) and the Hubble Space Telescope.

Hedgehog: An Isolated Quiescent Dwarf Galaxy at 2.4 Mpc

The Astrophysical Journal Letters
It is well known that almost all isolated dwarf galaxies are actively forming stars. We report the discovery of dw1322m2053 (nicknamed Hedgehog), an isolated quiescent dwarf galaxy at a distance of 2.40 ± 0.15 Mpc with a stellar mass of M _⋆ ≈ 10 ^5.8 M ...

The Dependence of Dark Matter Halo Properties on the Morphology of Their Central Galaxies from Weak Lensing

The Astrophysical Journal
Xu & Jing reported a monotonic relationship between the host halo mass M _h and the morphology of massive central galaxies, characterized by the Sérsic index n , at fixed stellar mass, suggesting that morphology could serve as a good secondary proxy for ...

The Importance of Gas Starvation in Driving Satellite Quenching in Galaxy Groups at z ~ 0.8

The Astrophysical Journal
We present results from a Keck/DEIMOS survey to study satellite quenching in group environments at z  ~ 0.8 within the Extended Groth Strip (EGS). We target 11 groups in the EGS with extended X-ray emission. We obtain high-quality spectroscopic redshifts

The Quenching of Cluster Galaxies

In this thesis we present two projects investigating the evolution and quenching of cluster galaxy star formation (SF) activity. Leveraging a sample of 36 galaxy clusters, we measure the level of member SF activity. Over the 7.5 billion years spanned by our clusters, from z=1.5 to z=0.15, the SF activity of cluster galaxies decreases by a factor of 11.

Investigating quenching in Recently Quenched Elliptical galaxies with HI studies

Recently Quenched Elliptical galaxies (RQEs) represent a critical phase in the transition from star-forming to quiescent galaxies. However, the mechanisms driving their quenching remain elusive. We conduct a multi-wavelength analysis of 155 RQEs, along with their precursors (preRQEs) and descendants (postRQEs), focusing on their neutral hydrogen (HI ...
