Deep rest-UV JWST/NIRSpec spectroscopy of early galaxies: the demographics of CIV and N-emitters in the reionization era
Michael W. Topping, Daniel P. Stark, Peter Senchyna +12
JWST has recently discovered a subset of reionization era galaxies with ionized gas that is metal poor in oxygen and carbon but heavily-enriched in nitrogen. This abundance pattern…
Metal-poor star formation at with JWST: new insight into hard radiation fields and nitrogen enrichment on 20 pc scales
Michael W. Topping, Daniel P. Stark, Peter Senchyna +11
Nearly a decade ago, we began to see indications that reionization-era galaxies power hard radiation fields rarely seen at lower redshift. Most striking were detections of nebular…
Small Region, Big Impact: Highly Anisotropic Lyman-continuum Escape from a Compact Starburst Region with Extreme Physical Properties
Keunho J. Kim, Matthew B. Bayliss, Jane R. Rigby +13
Extreme, young stellar populations are considered the primary contributor to cosmic re-ionization. How Lyman-continuum (LyC) escapes these galaxies remains highly elusive, and it i…
A variable active galactic nucleus at triply-imaged by the galaxy cluster MACS J0035.4-2015
Lukas J. Furtak, Ramesh Mainali, Adi Zitrin +32
We report the discovery of a triply imaged active galactic nucleus (AGN), lensed by the galaxy cluster MACS J0035.4-2015 (). The object is detected in Hubble…
Spectroscopy of CASSOWARY gravitationally-lensed galaxies in SDSS: characterisation of an extremely bright reionization-era analog at
Ramesh Mainali, Daniel P. Stark, Tucker Jones +3
We present new observations of sixteen bright () gravitationally lensed galaxies at selected from the CASSOWARY survey. Included in our sample is the $z=1.42…
The connection between galactic outflows and the escape of ionizing photons
Ramesh Mainali, Jane R. Rigby, John Chisholm +13
We analyze spectra of a gravitationally lensed galaxy, known as the Sunburst Arc, that is leaking ionizing photons, also known as the Lyman continuum (LyC). Magnification from grav…
