Double trouble: Two spectroscopically confirmed low-mass quiescent galaxies at z > 5 in overdensities

Astronomy & Astrophysics
We present the discovery of two low-mass, high-redshift quiescent galaxies, GS-z5-Q1 and COS-z5-Q1, using JWST NIRSpec spectroscopy alongside NIRCam and MIRI photometry.

Simulations All the Way Up! An Atheist's Response to the Fine‐Tuning Argument

Analytic Philosophy, EarlyView.
ABSTRACT So the Fine‐tuning Argument goes, because it is so unlikely for the physical constants of the laws of nature to have taken the values that they in fact take, we should significantly raise our credence that God exists. Simulation Arguments argue that our world might be (or, in stronger versions, that it probably is) a mere computer simulation ...

The star formation history of early-type galaxies in the fornax cluster [PDF]

, 1998
We have measured central line strengths and line-strength gradients for a complete sample of early-type galaxies in the Fornax cluster, comprising 11 elliptical and 11 lenticular galaxies, more luminous than M(_B) = -17.

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.

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.

The Problem of Psychonomic Harmony

Philosophy and Phenomenological Research, EarlyView.
ABSTRACT The problem of nomological harmony is the problem of explaining why the laws of nature match or apply to the states of the universe in a way that results in temporal evolution. The problem of psychophysical harmony is the problem of explaining why phenomenal states are paired with physical states and other phenomenal states in surprisingly ...

An infrared study of a sample of optically selected galaxies [PDF]

, 1987
Infrared and optical photometry of a complete sub-sample of 194 galaxies in the Anglo-Australian Redshift Survey is presented. The Colour-Redshift diagrams are constructed and used, in a self-consistent manner, to reduce the data to zero-redshift colours

The ATLAS(3D) project - XXV. Two-dimensional kinematic analysis of simulated galaxies and the cosmological origin of fast and slow rotators [PDF]

, 2014
We present a detailed two-dimensional stellar dynamical analysis of as ample of 44 cosmological hydrodynamical simulations of individual central galaxies with stellar masses of 2 x 1010Msun ∼≤ Mstar ∼≤ 6x 1011Msun.

On Our Cosmic (In)significance

Ratio, EarlyView.
ABSTRACT This article discusses three interpretations of cosmic significance, all of which reveal something important about the notion of significance. Along the way, it proposes a unified view of significance by combining elements of each of the views.

ELVES-Field: Isolated Dwarf Galaxy Quenched Fractions Rise below M∗ ≈ 107 M⊙

The Astrophysical Journal Letters
We use a new sample of low-mass ( M _*   10 ^9 M _⊙ . We find that, at higher dwarf masses ( M _⋆  ≳ 10 ^7 M _⊙ ), essentially all field dwarfs are star forming as has been found before. In contrast, at M _⋆  ≲ 10 ^7 M _⊙ , ∼30% of field dwarfs appear to
