High resolution polarization observations of spiral galaxies in far-infrared are enabling for the first time to study galactic magnetic fields deep into the...

BDS 1269 is a visual binary system with a Delta Scuti star as the primary (Mechler, 1974) and a normal early F main sequence secondary BDS 1269B (HD 15164)...

We present an abundance analysis based on high-resolution spectra of red-giant-branch (RGB) stars in the Galactic globular clusters NGC 6121 (M4) and NGC 6656...

The number of globular clusters plays a fundamental role in understanding the early stages of galaxy formation. We know that the GC population of normal...

It has been 20 years since the classification of galaxy disk types observed in deep imaging was established. These classifications, which notably consist of...

Using high-resolution spectra of 8 Active Galactic Nuclei (AGN) observed with INT we found that shapes of narrow emission lines indicate very complex structure...

The study of asteroids that present sporadic cometary activity, is of fundamental importance to address several astronomical problems like the end states of...
