We study the rotation rates and electric dipole emission of hydrogenated icosahedral fullerenes (single and multishell) in various phases of the interstellar medium. Using the formalism of Draine & Lazarian for the rotational dynamics of these molecules in various astrophysical environments, we find effective rotation rates in the range 1-65 GHz

Deep narrow-band (Brγ at 2.17μm and H_2 at 2.12μm) and broad-band (JHKs) near-infrared images are presented of the young regions Tr14-N4 and Car I. The observations were made with PANIC, attached to the Baade 6.5 m Magellan Telescope at Las Campanas Observatory. These were supplemented by archive Spitzer/IRAC images. Evidence is given of an

EMIR is one of the first common-user instruments for the GTC, the 10-meter telescope operating at the Roque de los Muchachos Observatory (La Palma, Canary Islands, Spain). EMIR is being built by a Consortium of Spanish and French institutes led by the Instituto de Astrofísica de Canarias (IAC). EMIR is primarily designed to be operated as a MOS in

A high-resolution optical spectrum of EX Lupi was obtained on 2007 July 30 with FEROS at the 2.2m MPG/ESO telescope in ESO La Silla, Chile. The spectrum shows several emission lines in addition to the photospheric absorption features characteristic of the young late-type star. Here we present all emission lines identified in the spectrum, the

The results of Hα photometry of a sample of early-type galaxies belonging to nearby compact groups are presented. Over 75% of the galaxies in the sample were detected in Hα, a result that we have interpreted as proof of the presence of a warm interstellar medium within them. Comparing the Hα luminosities of the galaxies in our sample with those of
