We present an optical and FIR analysis of a sample of 65 Lyα emitters at 2.0˜

Using optical-optical and optical-NIR colors, we analyze the radial dependence of age and metallicity inside massive (M sstarf >~ 1010.5 M sun), low-redshift (z 0.1), early-type galaxies (ETGs), residing in both high-density group regions and the field. On average, internal color gradients of ETGs are mainly driven by metallicity, consistent with

Comet 29P/Schwassmann-Wachmann 1 (hereafter SW1) is a primitive Centaur that exhibits continuous changes in its coma appearance and brightness [1]. Our team has recently completed a decade of photometric monitoring in order to infer the physicochemical processes behind the observed activity.

The flat-spectrum radio quasar PKS 1222+216 (4C+21.35, z = 0.432) was detected in the very high energy γ-ray band by MAGIC during a highly active γ-ray phase following an alert by the Large Area Telescope (LAT) onboard Fermi. Its relatively hard spectrum (70-400 GeV photon index Γ = 2.7 ± 0.3) without a cut off, together with its observed

We combine DensePak integral field unit and TAURUS Fabry-Perot observations of 13 nuclear rings to show an interconnection between the kinematic properties of the rings and their resonant origin. The nuclear rings have regular and symmetric kinematics, and lack strong non-circular motions. This symmetry, coupled with a direct relationship between

We present near-infrared spectra of 23 B-type asteroids obtained with the NICS cameraspectrograph at the 3.56 m Telescopio Nazionale Galileo. We also include visible and near-infrared spectra of 20 additional B-type asteroids from the literature, including near-Earth asteroid 1999 RQ36, primary target of NASA's OSIRIS-Rex sample return mission.
