Sown at Cosmic Dawn: Searching for Pop III Signatures in JWST JADES He II Selected Line Emitters
Rosa Roberts, Giorgia Riley, Christopher J. Conselice +4
Population III (Pop III) stars, the first generation of metal-free stars, remain undetected, partly because entirely pristine galaxies represent a short-lived phase. We instead tar…
Global trends in morphology from massive to dwarf galaxies
Ilin Lazar, Sugata Kaviraj, Christopher J. Conselice +7
The morphological properties of dwarf galaxies (Mstar < 10^9.5 MSun) remain largely unexplored, particularly outside the local neighbourhood. We explore how morphology changes acro…

Optical/infrared observations of the extraordinary GRB 250702B: a highly obscured afterglow in a massive galaxy consistent with multiple possible progenitors
Jonathan Carney, Igor Andreoni, Brendan O'Connor +31
GRB 250702B was the longest gamma-ray burst ever detected, with a duration that challenges standard collapsar models and suggests an exotic progenitor. We collected a rich set of o…
A dual AGN at z = 5.4 associated with a Lyman-alpha Nebula in the Center of a Cosmic Filament
Qiong Li, Christopher J. Conselice, Qiao Duan +9
Predictions from current theories and simulations suggest that dual AGN systems are exceedingly rare at high redshifts. The intense radiation and powerful outflows from AGNs regula…
