Chemical abundances and ionizing mechanisms in the star-forming double-ring of AM 0644-741 using MUSE data
V. M. A. Gómez-González, Y. D. Mayya, J. Zaragoza-Cardiel +6
We present the analysis of archival Very Large Telescope (VLT) Multi-Unit Spectroscopic Explorer (MUSE) observations of 179 HII regions in the star-forming double-ring collisional…
Nebular abundance gradient in the Cartwheel galaxy using MUSE data
Javier Zaragoza-Cardiel, V. Mauricio A. Gómez-González, Divakara Mayya +1
We here present the results from a detailed analysis of nebular abundances of commonly observed ions in the collisional ring galaxy Cartwheel using the Very Large Telescope (VLT) M…
On the contribution of the X-ray source to the extended nebular HeII emission in IZw18
C. Kehrig, M. A. Guerrero, J. M. Vilchez +1
Nebular HeII emission implies the presence of energetic photons (E54 eV). Despite the great deal of effort dedicated to understanding HeII ionization, its origin has remained…
Carbon dust in the evolved born-again planetary nebulae A30 and A78
J. A. Toalá, P. Jiménez-Hernández, J. B. Rodríguez-González +6
We present an infrared (IR) characterization of the born-again planetary nebulae (PNe) A30 and A78 using IR images and spectra. We demonstrate that the carbon-rich dust in A30 and…
The quantity of dark matter in early-type galaxies and its relation to the environment
A. Nigoche-Netro, G. Ramos-Larios, P. Lagos +5
We study the behavior of the dynamical and stellar mass inside the effective radius of early-type galaxies (ETGs) as a function of environment considering Newtonian dynamics, diffe…
The extended HeII4686 emission in the extremely metal-poor galaxy SBS0335-052E seen with MUSE
C. Kehrig, J. M. Vilchez, M. A. Guerrero +4
SBS0335-052E, one of the most metal-poor (Z ~ 3-4% Z) HeII-emitter starbursts known in the nearby universe, is studied using optical VLT/MUSE spectroscopic and Chandra X-…
