On the properties of the interstellar medium in extremely metal-poor blue compact dwarf galaxies. A VIMOS-IFU study of the cometary galaxy and Ly absorber Tol 65
P. Lagos, R. Demarco, P. Papaderos +5
In this study we present high-resolution VIsible Multi-Object Spectrograph integral field unit spectroscopy (VIMOS-IFU) of the extremely metal-poor HII/blue compact dwarf (BCD) gal…
Red galaxies with pseudo-bulges in the SDSS: closer to disk galaxies or to classical bulges?
B. Ribeiro, C. Lobo, S. Antón +2
Pseudo-bulges are expected to markedly differ from classical, quasi-monolithically forming bulges in their star formation history (SFH) and chemical abundance patterns. To test thi…
Extended nebular emission in CALIFA early-type galaxies
J. M. Gomes, P. Papaderos, C. Kehrig +3
The morphological, spectroscopic and kinematical properties of the warm interstellar medium (wim) in early-type galaxies (ETGs) hold key observational constraints to nuclear activi…
The warm ionized gas in CALIFA early-type galaxies: 2D emission-line patterns and kinematics for 32 galaxies
J. M. Gomes, P. Papaderos, C. Kehrig +23
The morphological, spectroscopic and kinematical properties of the warm interstellar medium (wim) in early-type galaxies (ETGs) hold key observational constraints to nuclear activi…
Spectroscopic aperture biases in inside-out evolving early-type galaxies from CALIFA
J. M. Gomes, P. Papaderos, J. M. Vílchez +21
Integral field spectroscopy studies based on CALIFA data have recently revealed the presence of ongoing low-level star formation (SF) in the periphery of ~10% of local early-type g…
Spiral-like star-forming patterns in CALIFA early-type galaxies
J. M. Gomes, P. Papaderos, J. M. Vílchez +21
Based on a combined analysis of SDSS imaging and CALIFA integral field spectroscopy data, we report on the detection of faint (24 < μ mag/arcsec < 26) star-forming spiral-a…
