On the Signature of Black Holes on the Quenched Stellar Mass Function
The Astrophysical JournalAs star-forming galaxies approach or exceed a stellar mass of around 10 ^11 M _⊙ , they are increasingly likely to be quenched in a process generically called mass quenching.

Risk Analysis, Volume 46, Issue 9, September 2026.ABSTRACT The Fermi paradox may partly reflect technological self‐destruction acting as a Great Filter during post‐industrial development. Because the empirical record consists of a single civilization observed over an eighty‐year nuclear age, the exercise reported here is best understood as a structured, historically anchored scenario analysis rather ...

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory
Astronomische Nachrichten, Volume 347, Issue 7, August 2026.ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Mergers, starbursts, and quenching in the SIMBA simulation
, 2019 We use the SIMBAcosmological galaxy formation simulation to investigate the relationship between major mergers (4:1), starbursts, and galaxy quenching.

The quenching of star formation in galaxies [PDF]
, 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.

PAC. V. The Roles of Mass and Environment in the Quenching of Galaxies
The Astrophysical JournalThe roles that mass and environment play in galaxy quenching are still under debate. Leveraging the Photometric objects Around Cosmic webs method, we analyze the excess surface distribution ${\bar{n}}_{2}{w}_{{\rm{p}}}({r}_{{\rm{p}}})$ of photometric ...

The clustering of galaxies in hierarchical galaxy formation models [PDF]
, 2010 Galaxy clustering encodes information about the values of cosmological parameters and also about the physical processes behind galaxy formation and evolution. The GALFORM semi-analytical model is the theoretical approach we used to model galaxy formation.

Comparing Inside-out and Outside-in Quenching Modes in MaNGA Observation and MaNGIA Simulation
The Astrophysical JournalThis 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.
