We present evidence that the very high energy (VHE, E> 100 GeV) gamma-ray emission
coincident with the supernova remnant IC 443 is extended. IC 443 contains one of the best …

In this paper, we report the results of spectroscopic and photometric observations of the
candidate evolved massive star MN48 disclosed via detection of a mid-infrared circular shell …

This paper presents multi-passband optical data obtained from observations of the Chandra
Deep Field South (CDF-S), located at,. The observations were conducted at the ESO/MPG …

Massive evolved stars lose a large fraction of their mass via copious stellar wind or instant
outbursts. During certain evolutionary phases, they can be identified by the presence of their …

A significant fraction of massive stars in the Milky Way and other galaxies are located far
from star clusters and star-forming regions. It is known that some of these stars are …

Magnetic fields are ubiquitous in galaxy clusters, yet their radial profile, power spectrum, and
connection to host cluster properties are poorly known. Merging galaxy clusters hosting …

ABSTRACT The Bullet cluster (1E 0657-55.8) is a massive merging system at redshift z=
0.296, known to host a powerful radio halo and a relic. Here we present high fidelity …

We have used the 2nd generation of the Guide Star Catalogue (GSC-II) as a reference
astrometric catalogue to compile the positions of 1086 Galactic Planetary Nebulae (PNe) …

Many radio galaxies show the presence of dense and dusty gas near the active nucleus.
This can be traced by both 21 cm H i absorption and soft X-ray absorption, offering new …

We report the discovery of a new Galactic candidate luminous blue variable (cLBV) via
detection of an infrared circular nebula and follow-up spectroscopy of its central star. The …
