The Metallicity Gradient of Sagittarius Dwarf Spheroidal Galaxy Prior to Infall Constrained by S-PLUS Observations of its Tidal Stream
Felipe Almeida-Fernandes, Guilherme Limberg, Hélio D. Perottoni +16
We study the metallicity distribution along the Sagittarius (Sgr) stream using photometric metallicities from S-PLUS DR4, combined with Gaia DR3 kinematics and APOGEE DR17 spectros…
The Universality of Dark Matter Density Profiles for Milky Way Analog Galaxies
Maria Clara Cavalcante-Siviero, K. Menéndez-Delmestre, P. P. B. Beaklini +4
The structure, extent, and mass of the Milky Way's (MW) dark matter (DM) halo are observationally challenging to determine due to our position within the Galaxy. To overcome this l…
Identifying a protocluster formation at z 4.5 in the COSMOS field: an extension of Taralay protocluster, traced by Ly-alpha emitters surrounding a submm galaxy
Mariana Rubet, KarÃn Menéndez-Delmestre, Thiago Signorini Gonçalves +4
We report the discovery of a large-scale structure containing multiple overdensities at in the COSMOS field, with the most prominent one likely infalling towards…
The S-PLUS Fornax Project (S+FP): Mapping globular clusters systems within 5 virial radii around NGC 1399
Luis LomelÃ-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…
On the Stellar Disk Vertical Scale Height of Edge-on Galaxies from SG
Notahiana Ranaivoharimina, Toky H. Randriamampandry, Jing Wang +2
Disk galaxies viewed as thin planar structures resulting from the conservation of angular momentum of an initially rotating pre-galactic cloud allow merely a first-order model of g…
