PublicaciónFar-infrared constraints on the contamination by dust-obscured galaxies of high-z dropout searches
The spectral energy distributions (SED) of dusty galaxies at intermediate redshift may look similar to very high-redshift galaxies in the optical/near infrared...

PublicaciónFirst Observation of the Submillimeter Polarization Spectrum in a Translucent Molecular Cloud
Polarized emission from aligned dust is a crucial tool for studies of magnetism in the ISM, but a troublesome contaminant for studies of cosmic microwave...

PublicaciónFirst results of an Hα based search of classical Be stars in the Perseus Arm and beyond
We investigate a region of the Galactic plane, between 120° ≤ ℓ ≤ 140° and -1° ≤ b ≤ +4°, and uncover a population of moderately reddened (E(B - V) ˜ 1)...

PublicaciónFractal dimension of optical cirrus in Stripe82
The geometric characteristics of dust clouds provide important information on the physical processes that structure such clouds. One of such characteristics is...

PublicaciónFullerenes and Buckyonions in the Interstellar Medium
We show that photoabsorption by fullerenes and buckyonions (multishell fullerenes) explain the shape, width, and peak energy of the most prominent feature of...

PublicaciónFullerenes as carriers of extinction, diffuse interstellar bands and anomalous microwave emission
According to semiempirical models, photoabsorption by fullerenes (single and multishell) could explain the shape, width and peak energy of the most prominent...

PublicaciónGaia Data Release 3. Exploring and mapping the diffuse interstellar band at 862 nm
Context. Diffuse interstellar bands (DIBs) are common interstellar absorption features in spectroscopic observations but their origins remain unclear. DIBs play...

PublicaciónGaia Focused Product Release: Spatial distribution of two diffuse interstellar bands
Diffuse interstellar bands (DIBs) are absorption features seen in optical and infrared spectra of stars and extragalactic objects that are probably caused by...
