Phoenix spectra of C_2, CN and CO lines will provide oxygen isotopic abundance ratios (^16O/^17O/^18O) and CNO abundances for cool R Coronae Borealis (RCB)...

It is widely accepted that starbursts can dramatically affect their host galaxies via feedback-driven outflows, especially for gas-rich dwarfs with shallow...

The Cocoon nebula is an apparently spherical Galactic HII region ionized by a single star (BD+46 3474). This nebula seems to be appropriate to investigate the...

A good alternative to traditional methods of passing on astronomical concepts is to use a 'collateral' story that catches the public's attention. It may also...

Years ago we have compiled all the available optical data in the literature to build a comprehensive classification of the low-ionization structures (LIS), as...

Numerical simulations of galaxy formation predict direct gas accretion from the cosmic web to be the main mode of disk galaxy formation. However, observational...

Equipartition of energy between relativistic particles and magnetic field is known to be consistent with observations in most of the large size (hundreds of kpc...

It was recently proposed that the Galactic binary system LB-1 hosts an ~8+70 solar mass B-star+black hole (BH) wide binary that is X-ray quiet, strongly...
