Evidence of a Forming Nucleus in the Fourcade–Figueroa Galaxy
The Astrophysical JournalWe analyze data from the IRAS, Wide-field Infrared Survey Explorer, and Planck satellites, revealing an unresolved dust condensation at the center of the Fourcade–Figueroa galaxy (ESO270-G017), which may correspond to a forming nucleus.

The Astrophysical JournalDetermining the inner structure of the molecular torus around an active galactic nucleus is essential for understanding its formation mechanism. However, spatially resolving the torus is difficult because of its small size.

Local Ultraluminous Infrared Galaxies and Quasars
, 2006 This paper reviews the recent results from a comprehensive investigation of the most luminous mergers in the local universe, the ultraluminous infrared galaxies (ULIRGs) and the quasars. First, the frequency of occurrence and importance of black hole driven nuclear activity in ULIRGs are discussed using the latest sets of optical, near-infrared, mid ...

Imaging of Ultraluminous Infrared Galaxies in the Near-UV
, 2000 We present the first ground-based U' (3410 angstroms) images of Ultraluminous Infrared Galaxies (ULIGs). Strong U' emission (median total M_U' = -20.8) is seen in all systems and in some cases the extended tidal features (both the smooth stellar distribution and compact star-forming features) contribute up to 60-80% of the total flux.

The Astrophysical JournalOne of the most remarkable discoveries of JWST is a population of compact, red sources at z > 4, commonly referred to as Little Red Dots (LRDs). Spectroscopic identifications reported that most LRDs are active galactic nuclei, which are preferentially ...

The Magnetic Fields of the Dusty Nuclei and Molecular Outflows of Arp 220
The Astrophysical Journal LettersGalaxy mergers trigger starburst activity and galactic outflows that enrich the circumgalactic medium (CGM), profoundly impacting galaxy evolution. These phenomena are intrinsically linked to the physical conditions of the medium, which is permeated by ...

Disclosing Submillimeter Galaxy Formation: Mergers or Secular Evolution?
The Astrophysical JournalWe analyze the morphology of 125 submillimeter galaxies (SMGs) in the PRIMER-COSMOS field using double Sérsic modeling on JWST NIRCam images across six bands (F150W, F200W, F277W, F356W, F410M, and F444W), with SMGs being classified by the bulge Sérsic ...

The Astrophysical Journal LettersThe study of heavily obscured supermassive black hole (SMBH) growth in late-stage galaxy mergers is challenging: column densities N _H > 10 ^24 cm ^−2 can block most nuclear emission, leaving significant gaps in the SMBH growth census.
