PublicaciónGalactic cirri in deep optical imaging
The ubiquitous presence of Galactic cirri in deep optical images represents a major obstacle to study the low surface brightness features of extragalactic...

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...

PublicaciónGas and Dust Emission from the Nuclear Region of the Circinus Galaxy
Simultaneous modeling of the line and continuum emission from the nuclear region of the Circinus galaxy is presented. Composite models that include the combined...

PublicaciónH α fluxes and extinction distances for planetary nebulae in the IPHAS survey of the northern galactic plane
We report H α filter photometry for 197 Northern hemisphere planetary nebulae (PNe) obtained using imaging data from the IPHAS survey. H α+[N II] fluxes were...

PublicaciónHerschel photometric observations of the low metallicity dwarf galaxy NGC 1705
We present Herschel SPIRE and PACS photometeric observations of the low metallicity (Z ~ 0.35 Z&sun;) nearby dwarf galaxy, NGC 1705, in six wavelength bands as...

PublicaciónHerschel-ATLAS: The dust energy balance in the edge-on spiral galaxy UGC 4754
We use Herschel PACS and SPIRE observations of the edge-on spiral galaxy UGC 4754, taken as part of the H-ATLAS SDP observations, to investigate the dust energy...

PublicaciónHerschel-SPIRE observations of the disturbed galaxy NGC 4438
We present Herschel-SPIRE observations of the perturbed galaxy NGC 4438 in the Virgo cluster. These images reveal the presence of extra-planar dust up to ~4-5...

PublicaciónHigh spatial resolution Galactic 3D extinction mapping with IPHAS
We present an algorithm (MEAD, for `Mapping Extinction Against Distance') which will determine intrinsic (r' - i') colour, extinction, and distance for early-A...
