Interaction-induced star formation boosts stellar mass assembly in galaxies
Kiyoaki C. Omori, Marcin Sawicki, Rosa M. Mérida +10
Galaxy interactions are a key ingredient in galaxy evolution; not only are they a primary pathway of galaxy growth and mass assembly, but also a key driver of processes such as sta…
CANUCS/Technicolor Data Release 2: A Catalogue of Galaxy Structural Parameters in up to 29 HST+JWST bands and a Multi-Wavelength Exploration of the Galaxy Size-Mass Relation at
Maya Merchant, Lamiya A. Mowla, Georgios E. Magdis +23
We present James Webb Space Telescope (JWST) results of a morphological study of galaxies in the CAnadian NIRISS Unbiased Cluster (CANUCS) and Technicolor surveys, observed in 19 m…
UV-to-optical insights into the BH model in little red dots
Rosa M. Mérida, Rosa M. Mérida, Marcin Sawicki +3
Little Red Dots (LRDs) are a heterogeneous class of objects, with several proposed scenarios for their physical nature and evolution. While these theories have been tested on indiv…
Testing the BH Model: a UV-to-Optical Spectral Fitting of The Cliff
Rosa M. Mérida, Marcin Sawicki, Gaia Gaspar +2
In the black hole star (BH*) model, the characteristic "V"-shaped SED of LRDs is produced by an accreting BH embedded in a dense neutral-gas envelope with a near-unity covering fac…
UV slopes of Starforming Galaxies in Strong Lensing fields at the Epoch of Reionization with JWST
Giordano Felicioni, MaruÅ¡a BradaÄ, Yoshihisa Asada +20
UV slopes () are a powerful diagnostics for galaxies at the Epoch of Reionization, tracing star formation, ISM ionization, and the escape fraction of ionizing photons…
The rise and fall of Little Red Dots could be driven by the environment
Rosa M. Mérida, Gaia Gaspar, Yoshihisa Asada +9
The Little Red Dot (LRD) paradigm comprises three main unknowns that are intrinsically connected: (1) What is the nature of these sources? (2) How do they form? (3) How do they evo…
