Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Jack Higginson, Jack Higginson, , , | Summary: We investigate the association between galaxies and neutral OI absorption systems at z~6, which trace metal-enriched gas during the epoch of reionization. We identify 40 galaxies across six quasar fields, residing in 15 overdensities within 300 kpc of […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: , , , , | Summary: We study the impact of warm dark matter (WDM) particle mass on galaxy properties using 1,024 state-of-the-art cosmological hydrodynamical simulations from the DREAMS project. We begin by using a Multilayer Perceptron (MLP) coupled with a normalizing flow to explore global statistical […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: , , , , | Summary: We report statistically significant detection of H I 21-cm emission from intermediate-redshift ($zapprox0.2$-0.6) galaxies. By leveraging multi-sightline galaxy survey data from the Cosmic Ultraviolet Baryon Survey (CUBS) and deep radio observations from the MeerKAT Absorption Line Survey (MALS), we have […]
Kavli Affiliate: Eric D. Miller | First 5 Authors: , , , , | Summary: We present the analysis of the intracluster light (ICL) in three fossil groups (FG), RXJ085640.72+055347.36, RX J1136+0713, and RX J1410+4145, at z ~ 0.1. We used two optical broad-band filters, F435W and F606W, observed with the Hubble Space Telescope and […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Eric Zhang, Eric Zhang, , , | Summary: It is often understood that supernova (SN) feedback in galaxies is responsible for regulating star formation and generating gaseous outflows. However, a detailed look at their effect on the local interstellar medium (ISM) on small mass scales in simulations […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Alberto Torralba, Alberto Torralba, , , | Summary: The population of the Little Red Dots (LRDs) may represent a key phase of supermassive black hole (SMBH) growth. A cocoon of dense excited gas is emerging as key component to explain the most striking properties of LRDs, […]
Kavli Affiliate: David P. Huenemoerder | First 5 Authors: Sean J. Gunderson, Sean J. Gunderson, , , | Summary: We present a multiwavelength analysis of the central stellar pair of $rho$ Oph, components A and B. Using recent high-resolution textitChandra X-ray Observatory observations, we demonstrate with high confidence that the dominant X-ray source is $rho$ […]
Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Hudson A. Loughlin, Hudson A. Loughlin, , , | Summary: Continuous-wave (CW) interferometry has stood at the frontier of precision measurement science since its inception, where it was used to search for the luminiferous ether, to the present day, where it forms the basis of interferometric gravitational-wave […]
Kavli Affiliate: Sara Seager | First 5 Authors: Julien de Wit, Julien de Wit, , , | Summary: Today’s most detailed characterization of exoplanet atmospheres is accessible via transit spectroscopy (TS). Detecting transiting exoplanets only yields their size, and it is thus standard to measure a planet’s mass before moving towards their atmospheric characterization, or […]
Kavli Affiliate: Erin Kara | First 5 Authors: Scott Hagen, Scott Hagen, , , | Summary: The accretion flow in AGN is not well understood, motivating intensive monitoring campaigns of multiwavelength variability to probe its structure. One of the best of these is the 3 year optical/UV/X-ray approximately daily monitoring campaign on Fairall,9, a fairly […]
