The central molecular gas structure in LINERs with low luminosity AGN: evidence for gradual disappearance of the torus
F. Müller-Sánchez, M. A. Prieto, M. Mezcua +3
We present observations of the molecular gas in the nuclear environment of three prototypical low luminosity AGN (LLAGN), based on VLT/SINFONI AO-assisted integral-field spectrosco…
The properties of the extended warm ionised gas around low-redshift QSOs and the lack of extended high-velocity outflows
B. Husemann, L. Wisotzki, S. F. Sánchez +1
(Abridged) We present a detailed analysis of a large sample of 31 low-redshift, mostly radio-quiet type 1 QSOs observed with integral field spectroscopy to study their extended emi…
CALIFA, the Calar Alto Legacy Integral Field Area survey. II. First public data release
CALIFA collaboration, B. Husemann, K. Jahnke +74
We present the first public data release of the CALIFA survey. It consists of science-grade optical datacubes for the first 100 of eventually 600 nearby (0.005<z<0.03) galaxies, ob…
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…
PyCosmic: a robust method to detect cosmics in CALIFA and other fiber-fed integral-field spectroscopy datasets
B. Husemann, S. Kamann, C. Sandin +3
[Abridged] Detecting cosmic ray hits (cosmics) in fiber-fed IFS data of single exposures is a challenging task, because of the complex signal recorded by IFS instruments. Existing…
A new scaling relation for HII regions in spiral galaxies: unveiling the true nature of the mass-metallicity relation
F. F. Rosales-Ortega, S. F. Sánchez, J. Iglesias-Páramo +5
We demonstrate the existence of a -local- relation between galaxy surface mass density, gas metallicity, and star-formation rate density using spatially-resolved optical spectrosco…
