Implicit inference of the reionization history with higher-order statistics of the 21-cm signal
Nicolas Cerardi, Sambit K. Giri, Michele Bianco +9
The Epoch of Reionization (EoR), when the first luminous sources ionised the intergalactic medium, represents a new frontier in cosmology. The Square Kilometre Array Observatory (S…
Exploring the Early Universe with Deep Learning
Emmanuel de Salis, Massimo De Santis, Davide Piras +9
Hydrogen is the most abundant element in our Universe. The first generation of stars and galaxies produced photons that ionized hydrogen gas, driving a cosmological event known as…
CHILES X: Molecular and atomic gas at intermediate redshift
Kelley M. Hess, John Hibbard, Jennifer Donovan Meyer +10
We present ALMA CO observations of 14 HI-detected galaxies from the CHILES survey found in a cosmic over-density at z~0.12. This is the largest collection of spatially resolved CO…
AMUSE-Antlia. II. Intracluster X-ray Population in the Antlia Cluster
Zhensong Hu, Yuanyuan Su, Zhiyuan Li +4
We conduct a systematic survey of X-ray sources in the inner ( kpc) region of the Antlia cluster based on \Chandra observations, down to a source detection limit of $ L(0…
Testing OH Megamaser Identification Methods in HI Surveys: Updated Source-Flagging Algorithms and New Detections in ALFALFA
Hayley Roberts, Jeremy Darling, Kelley M. Hess +3
OH megamasers (OHMs) are extragalactic masers found primarily in gas-rich galaxy major mergers. To date, only 120 OHMs have been cataloged since their discovery in 1982, and…
The RESOLVE and ECO G3 Initiative: Drivers of HI Content and X-ray Emission in Galaxy Groups
Zackary L. Hutchens, Sheila J. Kannappan, Kelley M. Hess +5
Adding to the RESOLVE and ECO Gas in Galaxy Groups (G3) initiative, we examine possible drivers of group-integrated HI-to-halo mass ratios () and group…
