The connection between galaxy mergers, star formation and AGN activity in the HSC-SSP

Kiyoaki Christopher Omori, Connor Bottrell, Sabine Bellstedt +6

Internal gas inflows driven by galaxy mergers are considered to enhance star formation rates (SFR), fuel supermassive black hole growth and stimulate active galactic nuclei (AGN).…

Lonely Little Red Dots: Challenges to the AGN-nature of little red dots through their clustering and spectral energy distributions

María Carranza-Escudero, Christopher J. Conselice, Nathan Adams +31

Observations with the James Webb Space Telescope (JWST) reveal a previously unseen population of compact red objects, known as ``little red dots`` (LRDs). We study a new photometri…

Correcting for the effects of the point spread function in intra-halo light measurements and application to deep Hyper Suprime-Cam data

L. P. Garate-Nuñez, A. S. G. Robotham, S. Bellstedt +1

The intra-halo light (IHL) is the diffuse stellar component that surrounds galaxies, groups, and clusters. Its formation is intimately linked to the hierarchical assembly of the sy…
