Colegas,

Los invitamos a participar del Ciclo de Coloquios del IAR el próximo lunes
11 de septiembre a las 13.30 h. En esta oportunidad, la Dra. Amanda Reis
Lopes, del Instituto de Astrofísica de La Plata (IALP), nos hablará sobre
el estudio de fuentes con líneas de emisión con el S-PLUS.

¡Esperamos contar con la participación de todos!

Saludos cordiales,

Florencia

Título:  Studying emission line sources with S-PLUS

Resumen: The analysis of emission lines in astrophysical sources
enables us to gain insight into the nature of the object, such as the
density of the ionizing gas. Furthermore, the emission map associated
with the HI image can provide us with a better understanding of the
physical processes occurring in these sources. The filter
configuration of the Southern Photometric Local Universe Survey
(S-PLUS), a wide field 12 band (5 broad and 7 narrow) survey observing
the Southern Sky, is ideal to detect emission by the combination of
narrow and broad bands. To investigate Halpha emitters sources, we
developed a code named P.E.L.E. (Pixel-to-pixel Emission Line
Estimate) that combines S-PLUS images using the Three Filter Method to
create emission line maps. We selected galaxies from the Fornax
cluster to evaluate P.E.L.E., as the Halpha line is situated in the
J0660 band at Fornax distance and there are already a few published
Halpha maps from the Fornax 3D project that can be compared to our
results. A second method to detect emission relies in the combination
of color-color plots, which is efficient to search for Extreme
Emission Line Galaxies (EELGs), which  are low-metallicity
star-forming galaxies that can be regarded as local analogs of
galaxies in the early Universe. In this talk, we will discuss our two
methodologies to identify emission, the first focus on the Fornax
members and some preliminary tests on planetary nebulae in the Small
Magellanic Cloud, and the second used to identify EELG at z<0.05.
