The quenching of star formation in galaxies [PDF]

open access: yes, 2018
This thesis is concerned with investigating what makes star formation inefficient in galaxies. Cosmological, hydrodynamical simulations of galaxy formation show that the energy produced in stars, supernova explosions and active galactic nuclei must couple back into a galaxy’s interstellar medium to prevent excess star formation.

Comparing Inside-out and Outside-in Quenching Modes in MaNGA Observation and MaNGIA Simulation

open access: yesThe Astrophysical Journal
This study probes the inside-out and outside-in quenching status of galaxies to understand the internal and external quenching sources responsible and their roles in galaxy evolution.

BEACON: JWST NIRCam Pure-parallel Imaging Survey. IV. A Systematic Search for Galaxy Overdensities and Evidence for Gas Accretion Mode Transition

open access: yesThe Astrophysical Journal
We systematically search for galaxy overdensities using 20 independent fields with a minimum of six filters (F090W, F115W, F150W, F277W, F356W, and F444W) from BEACON, the JWST Cycle 2 NIRCam pure-parallel imaging survey.

The Heavy Metal Survey: The Evolution of Stellar Metallicities, Abundance Ratios, and Ages of Massive Quiescent Galaxies since z ∼ 2

open access: yesThe Astrophysical Journal
We present the elemental abundances and ages of 19 massive quiescent galaxies at z ∼ 1.4 and z ∼ 2.1 from the Keck Heavy Metal Survey. The ultradeep LRIS and MOSFIRE spectra were modeled using a full-spectrum stellar population fitting code with variable

Clues to inside-out quenching in quiescent galaxies at 1.2 ≲ z ≲ 2.2: Age, Fe-, and Mg-abundance gradients from JWST-SUSPENSE

open access: yesAstronomy & Astrophysics
Spatially resolved stellar populations of massive quiescent galaxies at cosmic noon provide powerful insights into star-formation quenching and stellar mass assembly mechanisms.

Astrophysical black holes: An explanation for the galaxy quenching

open access: yesJournal of High Energy Astrophysics
In light of increasing observational evidence supporting the existence of ultra-compact objects, we adopt the term astrophysical black hole to refer to any object having a huge mass confined within a sufficiently small region of spacetime. This terminology encompasses both the classical black hole solutions predicted by general relativity, as well as ...

SDSS-C4 3028: the Nearest Blue Galaxy Cluster Devoid of an Intracluster Medium

open access: yesThe Open Journal of Astrophysics
SDSS-C4 3028 is a galaxy cluster at $z=0.061$, notable for its unusually high fraction of star-forming galaxies with 19 star-forming and 11 quiescent spectroscopically-confirmed member galaxies. From Subaru/HSC imaging, we derived a weak lensing mass of $

Environmental quenching of high-redshift galaxies: Interpreting JWST observations with simulations

open access: yesAstronomy & Astrophysics
Recent observations of the high-redshift Universe (z > 3), particularly with the James Webb Space Telescope (JWST), have revealed a population of quenched galaxies that challenges current galaxy formation models, which systematically underpredict their ...
