Source Finding and Characterisation for SKAO Science
Sabyasachi Pal, Souvik Manik, M Carmen Toribio +8
The advancements in highly sensitive and powerful radio telescopes, including the Square Kilometre Array Observatory (SKAO) and its precursors, MeerKAT, ASKAP, MWA, and HERA, will…
JWST Reveals Compact Nuclear Starbursts Masquerading as AGNs in Metal-Poor Dwarfs: Where Are the Accreting Intermediate-Mass Black Holes?
William Matzko, Shobita Satyapal, Jeffrey D. Mckaig +19
We present JWST/NIRSpec spectroscopy of the low-mass, metal-poor galaxy SDSS~J160135.95+311353.7 (J1601), selected for its extreme mid-infrared colors and compact nuclear emission,…
Probing the Nature of Lyman Continuum Emitting and Low-metallicity Galaxies Using the SKA
Omkar Bait, Daniel Schaerer, Mark Sargent
The sources responsible for cosmic reionization remain a key open question in observational cosmology. Recent JWST results increasingly suggest that low-mass star-forming galaxies…
Radio Spectral Energy Distribution of Low- Metal Poor Extreme Starburst Galaxies: Novel insights on the escape of ionizing photons
Omkar Bait, Daniel Schaerer, Yuri I. Izotov +1
Recent optical surveys have identified a rare population of low- () extreme star-forming galaxies (xSFGs) characterized by very low metallicity, strong emiss…
The Lyman-alpha and Continuum Origins Survey II: the connection between the escape of ionizing radiation and Lyman-alpha halos in star-forming galaxies
A. Saldana-Lopez, M. J. Hayes, A. Le Reste +24
One of the current challenges in galaxy evolution studies is to establish the mechanisms that govern the escape of ionizing radiation from galaxies. Here, we investigate the connec…
SKA-Low simulations for a cosmic dawn/epoch of reionisation deep field
Anna Bonaldi, Philippa Hartley, Simon Purser +7
We present a realistic simulation of an SKA-Low cosmic dawn/epoch of reionisation (CD/EoR) observation, which can be used to further the development of foreground-mitigation approa…
