The Suppression of Star Formation and the Effect of Galaxy Environment in Low-Redshift Galaxy Groups

, 2012
Understanding the interaction between galaxies and their surroundings is central to building a coherent picture of galaxy evolution. Here we use GALEX imaging of a statistically representative sample of 23 galaxy groups at z=0.06 to explore how local and

The UV properties of E+A galaxies: constraints on feedback-driven quenching of star formation [PDF]

, 2007
We present the first large-scale study of E+A (post-starburst) galaxies that incorporates photometry in the ultraviolet (UV) wavelengths. We find that the starburst that creates the E+A galaxy typically takes place within the last Gyr and creates a high ...

Galaxy evolution in groups and clusters: satellite star formation histories and quenching timescales in a hierarchical Universe [PDF]

, 2012
Satellite galaxies in groups and clusters are more likely to have low star formation rates (SFR) and lie on the red-sequence than central (field) galaxies.

Scintillation Response of 0D Cs3Cu2I5 Thin Layers to Light‐ and Heavy‐Ion Irradiation

Advanced Photonics Research, EarlyView.
Driven by increasing interest in uncovering the remarkable photoluminescence quantum yield of Cs3Cu2I5, polycrystalline thin layers are synthesized to investigate its radioluminescence response to energetic ions. Its spectroscopic capability is assessed in a wide range of ion mass and internal excitation processes are explored.

ELUCID IV: Galaxy Quenching and its Relation to Halo Mass, Environment, and Assembly Bias

, 2017
We examine the quenched fraction of central and satellite galaxies as a function of galaxy stellar mass, halo mass, and the matter density of their large scale environment.

Gone after one orbit: How cluster environments quench galaxies [PDF]

, 2019
The effect of galactic orbits on a galaxy's internal evolution within a galaxy cluster environment has been the focus of heated debate in recent years.

Quenching time-scales of galaxies in the eagle simulations

Monthly Notices of the Royal Astronomical Society, 2019
We use the \eagle\ simulations to study the connection between the quenching timescale, $ _{\rm Q}$, and the physical mechanisms that transform star-forming galaxies into passive galaxies. By quantifying $ _{\rm Q}$ in two complementary ways - as the time over which (i) galaxies traverse the green valley on the colour-mass diagram, or (ii) leave the ...

Revealing the Impact of Critical Stellar Central Density on Galaxy Quenching through Cosmic Time

The Astrophysical Journal
In a previous work, we investigated the structural and environmental dependence on quenching in the nearby universe. In this work, we extend our investigations to higher redshifts by combining galaxies from the Sloan Digital Sky Survey and The FourStar ...

ELVES. III. Environmental Quenching by Milky Way–mass Hosts

The Astrophysical Journal, 2023
Isolated dwarf galaxies usually exhibit robust star formation but satellite dwarf galaxies are often devoid of young stars, even in Milky Way–mass groups.

Isolated Neutron Stars as Science Validation for XMM2ATHENA: Ensuring Robust Data for Future X‐Ray Astronomy

Astronomische Nachrichten, EarlyView.
ABSTRACT The discovery of radio‐quiet, x‐ray thermally emitting isolated neutron stars (XINSs) in the ROSAT All‐Sky Survey revealed a previously overlooked component of the neutron star population. Advancements in x‐ray instrumentation and the availability of deep, wide‐area optical surveys now enable us to explore XINSs at fainter x‐ray fluxes and ...
