The interstellar medium is an excellent laboratory to test physical processes that cannot be reproduced in Earth-based laboratories. In this study several...
Confronting fuzzy dark matter with the rotation curves of nearby dwarf irregular galaxies
Dark matter is an invisible substance that makes up more than eighty percent of the matter content of the universe. We know of its existence due to its...
Constraints on the dust extinction law of the Galaxy
This work explores data from a few surveys, most notably the serendipitous catalogue from the NASA SWIFT mission that made use of the NUV/optical camera UVOT...
Cosmic amorphous dust in the interstellar medium as a possible explanation for the Anomalous Microwave Emission
The main emission mechanisms of the interstellar medium (ISM) in the spectral range between the radio and the far infrared are very well characterised and...
Stellar ages are key to several fields of astrophysics such as exoplanet research, galactic-archeology, and of course stellar physics. Obtaining the ages of...
Detection of TiO and Na in the atmosphere of the hot Jupiter HAT-P-65b
We present the low-resolution transmission spectra of the puffy hot Jupiter HAT-P-65b (0.53 MJup, 1.89 RJup, Teq = 1930 K), based on two transits observed using...
Discovery of a massive black hole companion to a B-type star from radial velocity measurements
All stellar-mass black holes have hitherto been identified by X-rays emitted from gas that is accreting onto the black hole from a companion star. These systems...
Discovery of a young forming planet around the nearby star AU Mic
AU Microscopii (AU Mic) is the second closest pre-main-sequence star, at a distance of 9.79 parsecs and with an age of 22 million years . AU Mic possesses a...
Discovery of continuous infrared winds during the outburst of a black hole
X-ray binaries are stellar systems composed of a compact object (either a stellar-mass black hole or a neutron star) and a donor star that transfers mass to the...
