Integral field spectroscopy of a sample of nearby galaxies: II. Properties of the H ii regions
S. F. Sanchez, F. F. Rosales-Ortega, R. A. Marino +17
In this work we analyze the spectroscopic properties of a large number of H ii regions, \sim2600, located in 38 galaxies. The sample of galaxies has been assembled from the face-on…
Hα Kinematics of S4G spiral galaxies-I. NGC 864
Santiago Erroz-Ferrer, Johan H. Knapen, Joan Font +22
We present a study of the kinematics of the isolated spiral galaxy NGC 864, using Hα Fabry-Perot data obtained with the GHαFaS instrument at the William Herschel Telescope in La Pa…
Integral Field Spectroscopy and multi-wavelength imaging of the nearby spiral galaxy NGC5668: an unusual flattening in metallicity gradient
Raffaella Anna Marino, Armando Gil de Paz, Africa Castillo-Morales +7
We present the analysis of the full bi-dimensional optical spectral cube of the nearby spiral galaxy NGC 5668, observed with the PPAK IFU at the Calar Alto observatory 3.5m telesco…
Early type galaxies with tidal debris and their scaling relations in the Spitzer Survey of Stellar Structure in Galaxies (S4G)
Taehyun Kim, Kartik Sheth, Joannah L. Hinz +21
Tidal debris around galaxies can yield important clues on their evolution. We have identified tidal debris in 11 early type galaxies (T \leq 0) from a sample of 65 early types draw…
A Study of Heating and Cooling of the ISM in NGC 1097 with Herschel-PACS and Spitzer-IRS
P. Beirao, L. Armus, G. Helou +38
NGC 1097 is a nearby Seyfert 1 galaxy with a bright circumnuclear starburst ring, a strong large-scale bar and an active nucleus. We present a detailed study of the spatial variati…
The S4G perspective on circumstellar dust extinction of AGB stars in M100
Sharon E. Meidt, Eva Schinnerer, Juan-Carlos Munoz-Mateos +19
We examine the effect of circumstellar dust extinction on the near-IR contribution of asymptotic giant branch (AGB) stars in intermediate-age clusters throughout the disk of M100.…
