Do some environments favor efficient conversion of molecular gas into stars? To answer this, we need to be able to estimate the H2 mass. Traditionally, this is...

Spectroscopy and mapping of the type I postmain-sequence source CRL 618, taken with the 45-m antenna of the Nobeyama Radio Observatory and the 12-m NRAO...

We report the discovery of a low-mass (0.26 +/- 0.02, 0.15 +/- 0.01Msolar) pre-main-sequence (PMS) eclipsing binary (EB) with a 5.3d orbital period. JW 380 was...

During the first billion years of their life, exoplanet atmospheres are modified by different atmospheric escape phenomena that can strongly affect the shape...

We present a new catalogue of EROs from the Groth Strip and study the relation between their morphology and mass. With a selection criterion F814W-Ks≥ 4 and Ks≤...

The bulge of the Galaxy is analyzed by inverting K-band star counts from the Two-Micron Galactic Survey in a number of off-plane regions. A total area of about...

We present photometric and spectroscopic observations of the members of three previously cataloged compact group (CG) candidates at redshifts z > 0.3. These...

We present 1.3- and/or 3-mm continuum images and 3-mm spectral scans, obtained using Northern Extended Millimeter Array (NOEMA) and Atacama Large Millimeter...

High spatial resolution near-infrared (NIR) images of the central 24 × 24 arcsec2 (˜2 × 2 kpc2) of the elliptical galaxy NGC 1052 reveal a total of 25 compact...
