We present an atlas of Ks-band images of 206 early-type galaxies, including 160 S0-S0/a galaxies, 12 ellipticals and 33 Sa galaxies (+ one later type). The...
Near-Infrared Galaxy Counts and Evolution from the Wide-Field ALHAMBRA Survey
The ALHAMBRA survey aims to cover 4 deg2 using a system of 20 contiguous, equal width, medium-band filters spanning the range 3500 Å-9700 Å plus the standard...
Near-infrared imaging of the host galaxies of flat spectrum radio quasars
We present the results of a high resolution (0.27'' px(-1) ) near-infrared H band (1.65 μm) imaging survey of a complete sample of 20 flat spectrum radio...
Near-infrared imaging of the Seyfert 2 galaxy NGC 5252.
We present near-infrared (JHK) imaging of the Seyfert 2 galaxy NGC 5252, taken with the IRAC2 array on the 2.2m telescope at ESO, La Silla. The unresolved and...
Near-infrared line-strengths in elliptical galaxies: evidence for initial mass function variations?
We present new relations between recently defined line-strength indices in the near-infrared (CaT*, CaT, PaT, MgI and sTiO) and central velocity dispersion (σ0)...
Near-Infrared Observations of BL Lacertae Host Galaxies
Multiband near-infrared images of 12 BL Lacertae objects were obtained with the 2.5 m telescope at the Las Campanas Observatory in order to determine the...
Near-infrared spectroscopic indices for unresolved stellar populations. III. Composite indices definition as age and metallicity tracers and model comparison
Recent advances in the stellar population studies of unresolved galaxies in the NIR domain demonstrated that it contains several line-strength indices to be...
Near-infrared spectroscopy of nearby Seyfert galaxies - I. First results
We present near-infrared 1.5-2.5μm moderate-resolution long-slit spectra of two Seyfert 1 galaxies (NGC 1097 and 1566), three Seyfert 2s (NGC 1386, 4945 and...
Near-infrared spectroscopy of nearby Seyfert galaxies - II. Molecular content and coronal emission
We present subarcsec near-infrared 1.5-2.5 μm moderate resolution long-slit spectra of eight nearby Seyfert galaxies (z 0.01), both parallel to the ionization...
