Searching for Binary Black Hole Merger Emission in AGN Disks: Optical and Spectroscopic Follow-up of S240413p

P. Darc, C. R. Bom, A. Santos +7

The conditions under which binary black hole (BBH) mergers embedded in active galactic nucleus (AGN) disks produce detectable optical counterparts remain poorly constrained observa…

The S-PLUS Fornax Project (S+FP): An extragalactic catalog covering 5 virial radii around NGC 1399 with galaxy properties

R. F. Haack, A. V. Smith Castelli, L. Sodré +22

Observational extragalactic catalogs over wide sky areas are essential for uncovering the large-scale structure of the Universe. They allow, among others, cosmological studies and…

The homogeneity scale in the Local Universe: model-independent estimate from S-PLUS DR4 blue galaxies

Camila Franco, Felipe Avila, Armando Bernui +8

We present a model-independent estimate of the angular homogeneity scale in the Local Universe by analysing data from the Southern Photometric Local Universe Survey (S-PLUS). Two c…

Targeting cluster galaxies for the 4MOST CHANCES Low-z sub-survey with photometric redshifts

Hugo Méndez-Hernández, Ciria Lima-Dias, Antonela Monachesi +54

The evolution of galaxies is shaped by both internal processes and their external environments. Galaxy clusters and their surroundings provide ideal laboratories to study these eff…

Long-Term Optical Follow Up of S231206cc: Multi-Model Constraints on BBH Merger Emission in AGN Disks

P. Darc, C. R. Bom, C. D. Kilpatrick +9

The majority of gravitational wave events detected by the LIGO, Virgo, and KAGRA Collaboration originate from binary black hole (BBH) mergers, for which no confirmed electromagneti…

The S-PLUS Fornax Project (S+FP): Mapping globular clusters systems within 5 virial radii around NGC 1399

Luis Lomelí-Núñez, A. Cortesi, A. V. Smith Castelli +25

We present the largest sample (13,000 candidates, 3000 of wich are bona-fide candidates) of globular cluster (GCs) candidates reported in the Fornax Cluster so far. The…
