The meson decays B →D τ ν and B →D *τ ν are sensitive probes of the b →c τ ν transition. In this work, we present a complete framework to obtain the maximum...

We present the analysis of nine radio sources belonging to the Third Cambridge Revised catalog (3CR) observed with Chandra during Cycle 20 in the redshift range...

Context. The z ∼ 0.1 type-2 QSO J1430+1339, known as the " Teacup", is a complex galaxy showing a loop of ionised gas ∼10 kpc in diameter, co-spatial radio...

We investigate three barred lenticular galaxies (NGC 2681, NGC 3945 and NGC 4371), which were previously reported to have complex central structures but without...

In this work, we study the physical and kinematical properties of the emission line region of the Seyfert 1.5 galaxy Mrk 817 using three sets of observations...

We present bidimensional spectroscopy of the circumnuclear region of the Seyfert galaxy NGC 3227. The physical and kinematical characteristics of the two...

We address one of the lingering mysteries of high-velocity clouds: If the anomalous negative velocities are the result of the approaching gas from old...

We investigate the nature of the broad-band emission associated with the low-power radio hotspots 3C 105 South and 3C 445 South. Both hotspot regions are...

We present a spectroscopic component analysis of 18 candidate young, wide, non-magnetic, double-degenerate binaries identified from a search of the Sloan...
