Inferring the Morphology of Stellar Distribution in TNG50: Twisted and Twisted-Stretched shapes
Razieh Emami, Lars Hernquist, Charles Alcock +9
We investigate the morphology of the stellar distribution in a sample of Milky Way (MW) like galaxies in the TNG50 simulation. Using a local in shell iterative method (LSIM) as the…
The galaxy-halo connection of emission-line galaxies in IllustrisTNG
Boryana Hadzhiyska, Sandro Tacchella, Sownak Bose +1
We employ the hydrodynamical simulation IllustrisTNG-300-1 to explore the halo occupation distribution (HOD) and environmental dependence of luminous star-forming emission-line gal…
Degeneracies between baryons and dark matter: the challenge of constraining the nature of dark matter with JWST
Diana Khimey, Sownak Bose, Sandro Tacchella
The James Webb Space Telescope (JWST) will revolutionise our understanding of early galaxy formation, and could potentially set stringent constraints on the nature of dark matter.…
Measuring the mass and concentration of dark matter halos from the velocity dispersion profile of their stars
Sownak Bose, Abraham Loeb
We use the IllustrisTNG (TNG) cosmological, hydrodynamical simulations of galaxy formation to measure the velocity dispersion profiles of dark matter and star particles in Milky Wa…
Evidence for galaxy assembly bias in BOSS CMASS redshift-space galaxy correlation function
Sihan Yuan, Boryana Hadzhiyska, Sownak Bose +2
Building accurate and flexible galaxy-halo connection models is crucial in modeling galaxy clustering on non-linear scales. Recent studies have found that halo concentration by its…
DM halo morphological types of MW-like galaxies in the TNG50 simulation: Simple, Twisted, or Stretched
Razieh Emami, Shy Genel, Lars Hernquist +8
We present a comprehensive analysis of the shape of dark matter (DM) halos in a sample of 25 Milky Way-like galaxies in TNG50 simulation. Using an Enclosed Volume Iterative Method…
Extensions to models of the galaxy-halo connection
Boryana Hadzhiyska, Sownak Bose, Daniel Eisenstein +1
We explore two widely used empirical models for the galaxy-halo connection, subhalo abundance matching (SHAM) and the halo occupation distribution (HOD) and compare their predictio…
The BUFFALO HST Survey
Charles L. Steinhardt, Mathilde Jauzac, Ana Acebron +91
The Beyond Ultra-deep Frontier Fields and Legacy Observations (BUFFALO) is a 101 orbit + 101 parallel Cycle 25 Hubble Space Telescope Treasury program taking data from 2018-2020. B…
