Ionizing stellar population in the disc of NGC 3310 - II. The Wolf-Rayet population
D. Miralles-Caballero, F. F. Rosales-Ortega, A. I. Díaz +3
We use integral field spectroscopy to study in detail the Wolf-Rayet (WR) population in NGC 3310, spatially resolving 18 star-forming knots with typical sizes of 200-300 pc in the…
The behavior of the pitch angle of spiral arms depending on optical wavelength
Eric E. Martínez-García, Ivânio Puerari, F. F. Rosales-Ortega +3
Based on integral field spectroscopy data from the CALIFA survey, we investigate the possible dependence of spiral arm pitch angle with optical wavelength. For three of the five st…
Understanding chemical evolution in resolved galaxies -- I The local star fraction-metallicity relation
Y. Ascasibar, M. Gavilán, N. Pinto +3
This work studies the relation between gas-phase oxygen abundance and stellar-to-gas fraction in nearby galaxies. We first derive the theoretical prediction, and argue that this re…
The Mice at play in the CALIFA survey: A case study of a gas-rich major merger between first passage and coalescence
Vivienne Wild, Fabian Rosales-Ortega, Jesus Falcon-Barroso +43
We present optical integral field spectroscopy (IFS) observations of the Mice, a major merger between two massive (>10^11Msol) gas-rich spirals NGC4676A and B, observed between fir…
A study of the ionized gas in Stephan's Quintet from integral field spectroscopy observations
M. Rodriguez-Baras, F. F. Rosales-Ortega, A. I. Diaz +2
The Stephan's Quintet (SQ) is a famous interacting compact group of galaxies in an important stage of dynamical evolution, but surprisingly very few spectroscopic studies are found…
Ionizing stellar population in the disk of NGC 3310 I. The impact of a minor merger on galaxy evolution
D. Miralles-Caballero, A. I. Díaz, F. F. Rosales-Ortega +2
Numerical simulations of minor mergers predict little enhancement in the global star formation activity. However, it is still unclear the impact they have on the chemical state of…
