Tracing Lyman alpha escape in the CRISTAL-02 galaxy at z~5.3
Arshi Ali, Lucia Guaita, Manuel Aravena +20
We investigate the mechanisms regulating Lyman-alpha (Ly) escape in the star-forming galaxy CRISTAL-02 at z~5.3. The galaxy has clumpy morphology, suggestive that it may be inte…
An extreme ram-pressure stripping event in a protocluster at redshift 4.3
Dazhi Zhou, Scott C. Chapman, Manuel Aravena +16
In the nearby Universe, the environment plays a crucial role in suppressing star formation in dense regions. In particular, ram-pressure stripping (RPS) is a major mechanism for re…
JWST's PEARLS: A clumpy ring galaxy at
David Vizgan, Ming-Yang Zhuang, Ian Smail +22
Ring galaxies are an uncommon class of galaxies whose morphology is closely related to dynamical processes that govern galaxy evolution. Some ring galaxies, known as "collisional r…
A census of star-formation and gas mass tracers in two lensed dusty star-forming galaxies
David Vizgan, Joaquin D. Vieira, Justin S. Spilker +20
We present new and archival Atacama Large Millimeter/submillimeter Array (ALMA) observations of two strongly lensed dusty star-forming galaxies (DSFGs) selected from the South Pole…
Hiding behind a curtain of dust: Gas and dust properties of an ultra-luminous strongly-lensed z = 3.75 galaxy behind the Milky Way disk
Belén Alcalde Pampliega, Kevin C. Harrington, Aristeidis Amvrosiadis +21
We present a detailed analysis of J154506, a strongly lensed submillimeter galaxy behind the Lupus-I molecular cloud, and characterisation of its physical properties using a combin…
An Overabundance of Radio-AGN in the SPT2349-56 Protocluster: Preheating the Intra-Cluster Medium
Scott C. Chapman, Roger P. Deane, Dazhi Zhou +22
Following the detection of a radio-loud Active Galactic Nucleus (AGN) in the z=4.3 protocluster SPT2349-56, we have obtained additional observations with MeerKAT in S-band (2.4 GHz…
