The Fundamental Plane in the LEGA-C Survey: Unraveling the M/L Ratio Variations of Massive Star-forming and Quiescent Galaxies at z ∼ 0.8 [PDF]
Astrophysical Journal, 2021 We explore the connection between the kinematics, structures and stellar populations of massive galaxies at 0.6 < z < 1.0 using the fundamental plane (FP).

A fundamental plane in X-ray binary activity of external galaxies [PDF]
Nippon Tenmon Gakkai obun kenkyu hokoku, 2021 We construct a new catalog of extragalactic X-ray binaries (XRBs) by matching the latest Chandra source catalog with local galaxy catalogs. Our XRB catalog contains 4430 XRBs hosted by 237 galaxies within ∼130 Mpc.

Fundamental X-ray corona parameters of Swift/BAT AGN [PDF]
Monthly notices of the Royal Astronomical Society, 2021 While X-ray emission from active galactic nuclei (AGN) is common, the detailed physics behind this emission is not well understood. This is in part because high quality broad-band spectra are required to precisely derive fundamental parameters of X-ray

Dependence of the Fundamental Plane of Early-type Galaxies on Age and Internal Structure [PDF]
Astrophysical Journal, 2020 We investigate the scatter in the fundamental plane (FP) of early-type galaxies (ETGs) and its dependence on age and internal structure of ETGs, using 16,283 ETGs with Mr ≤ −19.5 and 0.025 ≤ z < 0.055 in Sloan Digital Sky Survey data. We use the relation

Evolution of Nonparametric Morphology of Galaxies in the JWST CEERS Field at z ≃ 0.8–3.0 [PDF]
Astrophysical Journal, 2023 Galaxy morphology is one of the most fundamental ways to describe galaxy properties, but the morphology we observe may be affected by wavelength and spatial resolution, which may introduce systematic bias when comparing galaxies at different redshift ...

The Observable Properties of Galaxy Accretion Events in Milky Way–like Galaxies in the FIRE-2 Cosmological Simulations [PDF]
Astrophysical Journal, 2022 In the Λ-Cold Dark Matter model of the universe, galaxies form in part through accreting satellite systems. Previous works have built an understanding of the signatures of these processes contained within galactic stellar halos.

ERGO-ML I: Inferring the assembly histories of IllustrisTNG galaxies from integral observable properties via invertible neural networks [PDF]
Monthly notices of the Royal Astronomical Society, 2022 A fundamental prediction of the ΛCDM cosmology is the hierarchical build-up of structure and therefore the successive merging of galaxies into more massive ones.

Is there a fundamental acceleration scale in galaxies? [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Milgrom's modified Newtonian dynamics (MOND) can explain well the mass discrepancy problem in galaxy without invoking dark matter. The MOND theory predicts a universal constant acceleration scale in galaxy, below which the Newtonian dynamics is no longer

Fundamental parameters of FR II radio galaxies and their impact on groups and clusters' environments [PDF]
, 2012 Radio galaxies are among the largest and most powerful single objects known and are found at variety of redshifts, hence they are believed to have had a significant impact on the evolving Universe.

Fundamental Plane of Elliptical Galaxies in f(R) Gravity: The Role of Luminosity [PDF]
Atoms, 2018 The global properties of elliptical galaxies are connected through the so-called fundamental plane of ellipticals, which is an empirical relation between their parameters: effective radius, central velocity dispersion and mean surface brightness within ...
