PublicaciónFullerenes in the IC 348 star cluster of the Perseus molecular cloud
We present the detection of fullerenes C60 and C70 in the star-forming region IC 348 of the Perseus molecular cloud. Mid-IR vibrational transitions of C60 and...

PublicaciónGalactic extinction laws - II. Hidden in plain sight, a new interstellar absorption band at 7700 Å broader than any known DIB
We have detected a broad interstellar absorption band centred close to 7700 Å and with a full width at half-maximum (FWHM) of 176.6 ± 3.9 Å. This is the first...

PublicaciónGalactic Interstellar Gas Cloud Mass Functions: A Simple Quantitative Approach
We present here a simple approach to understanding the gas cloud mass distribution function by simulating formation and destruction of gas clouds and gas clumps...

PublicaciónHigh-resolution spectroscopy of the Seyfert galaxy MRK 595 in the direction of the Cohen HI high-velocity stream
We have obtained a spectrum of the Na D lines of the Seyfert galaxy Mrk 595 with a signal-to-noise ratio (S/N) of about 30. The importance of this sightline is...

PublicaciónHigh-velocity clouds as dark matter in the Local Group
The High-Velocity Clouds (HVCs) observed in the Galactic neighbourhood, have been proposed to be remnants of the formation of the galaxies in the Local Group...

PublicaciónHydrogen volume densities in nearby galaxies - I. An automated approach
Using a simple model of photodissociated atomic hydrogen on a galactic scale, it is possible to derive total hydrogen volume densities. These densities...
