Dust is present everywhere in the Universe. Dust absorbs and scatters light dimming the astrophysical sources. Precise measurements of the attenuation...
Dust properties in the circumstellar shells of evolved stars: Observational constraints from ISO and Spitzer infrared spectroscopy
We present the results of a systematic analysis of the solid state features identified in the circumstellar environments of a large sample of evolved stars with...
Dust, gas, and metallicity in compact Galactic disk planetary nebulae: the missing evolutionary link
Planetary nebulae (PNe) are ideal probes of dust formation and evolution in low- and intermediate- mass stars. The analysis of dust emission in the 5 to 40...
The use of red colour as the basis for selecting candidate high redshift dusty galaxies from surveys made with Herschel has proved highly successful. The...
We have applied the InfraRed Flux Method (IRFM) to a sample of 475 dwarfs and subdwarfs in order to derive their effective temperatures with a mean accuracy of...
Dwarf ellipticals in the eye of SAURON: dynamical & stellar population analysis in 3D
We present the dynamical and stellar population analysis of 12 dwarf elliptical galaxies (dEs) observed using the SAURON IFU (WHT, La Palma). We demonstrate...
Dwarf galaxies in the Local Group: cornerstones for stellar astrophysics and cosmology
Dwarf galaxies have been the crossroad of significant theoretical and observational efforts, but we still lack firm constraints concerning their formation and...
Dwarf galaxy candidates around interacting galaxies (Deeg+ 1998)
The tables list positions, sizes and photometry in V and R band of extended objects found in fields, which include a nearby interacting galaxy. The tables'...
