The reddening law of Type Ia Supernovae: separating intrinsic variability from dust using equivalent widths [PDF]
Astronomy & Astrophysics, 2011 We employ 76 type Ia supernovae (SNe Ia) with optical spectrophotometry within 2.5 days of B-band maximum light obtained by the Nearby Supernova Factory to derive the impact of Si and Ca features on the supernovae intrinsic luminosity and determine a ...

The Reddening law outside the local group galaxies: The case of NGC 7552 and NGC 5236
The Astrophysical Journal, 1994 The dust reddening law from the UV to the near-IR for the extended regions of galaxies is here derived from the spectral distributions of the starburst spiral galaxies NGC 7552 and NGC 5236. The centers of these galaxies have similar absorption and emission line spectra, differing only if the strength of their interstellar lines and in the continuum ...

A NEW REDDENING LAW FOR M4 [PDF]
The Astronomical Journal, 2012 We have used a combination of broadband near-infrared and optical Johnson–Cousins photometry to study the dust properties in the line of sight to the Galactic globular cluster M4.

ANOMALOUSLY STEEP REDDENING LAW IN QUASARS: AN EXCEPTIONAL EXAMPLE OBSERVED IN IRAS 14026+4341 [PDF]
The Astronomical Journal, 2013 A fraction of the heavily reddened quasars require a reddening curve that is even steeper than that of the Small Magellanic Cloud. In this paper, we thoroughly characterize the anomalously steep reddening law in quasars via an exceptional example ...

The colour-lightcurve shape relation of type Ia supernovae and the reddening law [PDF]
Astronomy & Astrophysics, 2007 Aims. We present a study of the time sequence of optical colours of a large sample of nearby type Ia supernovae (SNe Ia). We study the dependence of the colour time-evolution on the lightcurve shape, parametrized by the stretch factor. Methods.

Red and infrared colours of B stars and the reddening law in the Galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 1997 The red and infrared intrinsic colours of B stars are derived from photometric observations through the UBV(R1)cJHK and H,8 filters of 257 early-type stars. Those stars for which the UBV and H,8 measurements match the published spectral class, and which show no other signs of peculiarity, are used to determine the intrinsic photometric colours of B ...

A Near-infrared Extinction and Reddening Map toward the Galactic Bulge Using UKIRT
The Astronomical JournalThe Galactic bulge is one of the most information-dense regions to study resolved stellar populations, variables, and transients, such as microlensing events.

The UV and Optical Reddening Law to the Galactic Bulge and CNO Abundances in Bulge Planetary Nebulae [PDF]
Symposium - International Astronomical Union, 1993 An analysis of the differential ultraviolet extinction towards four bulge planetary nebulae, based on the observed line ratio of He II 1640/4686Å, shows that the ultraviolet reddening law towards the bulge is much steeper than in the solar neighbourhood.
