Kavli Affiliate: Roberto Maiolino | First 5 Authors: Adam Marshall, Matthew W. Auger-Williams, Manda Banerji, Roberto Maiolino, Rebecca Bowler | Summary: We perform spectral energy distribution (SED) fitting to 711 luminous X-ray AGN at 0.7 < z < 4.5 using 10-bands of optical and infra-red photometric data for objects within XMM-SERVS. This fitting provided 510 […]

Kavli Affiliate: Savdeep Sethi | First 5 Authors: Christian Ferko, Savdeep Sethi, , , | Summary: We explore whether one can $T overline{T}$ deform a collection of theories that are already $T overline{T}$-deformed. This allows us to define classes of irrelevant deformations that know about subsystems. In some basic cases, we explore the spectrum that […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Yuki Isobe, Masami Ouchi, Kimihiko Nakajima, Shinobu Ozaki, Nicolas Bouche | Summary: We present kinematics of 6 local extremely metal-poor galaxies (EMPGs) with low metallicities ($0.016-0.098 Z_{odot}$) and low stellar masses ($10^{4.7}-10^{7.6} M_{odot}$). Taking deep medium-high resolution ($Rsim7500$) integral-field spectra with 8.2-m Subaru, we resolve the small […]

Kavli Affiliate: David N. Spergel | First 5 Authors: Drew Jamieson, Yin Li, Renan Alves de Oliveira, Francisco Villaescusa-Navarro, Shirley Ho | Summary: We build a field level emulator for cosmic structure formation that is accurate in the nonlinear regime. Our emulator consists of two convolutional neural networks trained to output the nonlinear displacements and […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Anirudh Chiti, Joshua D. Simon, Anna Frebel, Andrew B. Pace, Alexander P. Ji | Summary: We present a chemodynamical study of the Grus I ultra-faint dwarf galaxy (UFD) from medium-resolution ($Rsim11,000$) Magellan/IMACS spectra of its individual member stars. We identify eight confirmed members of Grus I, based […]
Kavli Affiliate: David N. Spergel | First 5 Authors: Drew Jamieson, Yin Li, Siyu He, Francisco Villaescusa-Navarro, Shirley Ho | Summary: We train a neural network model to predict the full phase space evolution of cosmological N-body simulations. Its success implies that the neural network model is accurately approximating the Green’s function expansion that relates […]
