Colegas,

les recordamos que hoy a las 13:30 hs. el Lic. Rodrigo Haack, nos contará
sobre los trabajos que está realizando en el marco de su tesis doctoral
utilizando datos del relevamiento S-PLUS. Esta tesis está siendo llevada a
cabo bajo la dirección de la Dra. Analía Smith en el Instituto de
Astrofísica de La Plata.

Debajo podrán ver la información sobre la charla que nos brindará.

La charla se llevará a cabo en modo presencial y también será transmitida

Coloquio a cargo del Lic. Rodrigo Haack

*Título: *Galaxy properties in the Eridanus-Fornax-Doradus filament with
S-PLUS + LePhare.

*Resumen: *In the context of the S-PLUS Fornax Project (S+FP), we have
obtained an extragalactic catalog containing homogeneous photometry for ~
65,000 galaxies located, in projection, in the direction of the Fornax
cluster, covering a sky area of ~ 208 square degrees around NGC 1399. A key
problem to be solved in order to identify possible substructures in the
spatial distribution of the objects included in that catalog, is to
reliably determine their redshifts. In this talk we will present the
strategy used to obtain the Extragalactic Catalog of the S+FP which
involved the application of  Machine Learning (ML) and Deep Learning (DL)
techniques on a total of 3 x 10^6 resolved and unresolved sources, to
identify and remove spurious objects and to perform a star/galaxy
separation. From the application to this catalog of template fitting
techniques, we were able to obtain preliminary photometric redshifts using
the photometry in the 12  bands of S-PLUS, complemented with GALEX,
VHS-Vista and WISE data. As a starting point, we expect such information
allows us to differentiate, at least with some degree of confidence,
background objects from possible Fornax members. This work represents the
initial steps of my PhD Thesis, which proposes the study of the
Doradus-Fornax-Eridanus filament with S-PLUS images.
