The Ultraviolet to Mid-infrared Extinction Law of the Taurus Molecular Cloud Based on the Gaia DR3, GALEX, APASS, Pan-STARRS1, 2MASS, and WISE Surveys

open access: yesThe Astrophysical Journal, 2023
Interstellar-dust extinction law is essential for interpreting observations. In this work, we investigate the ultraviolet (UV)–mid-infrared (IR) extinction law of the Taurus molecular cloud and its possible variations. We select 504,988 dwarf stars (4200

HST NIC3 Photometry of Metal-Rich Globular Clusters Palomar 6, Liller 1, and 47 Tuc (NGC 104) [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2004
We present HST NIC3 photometry of metal-rich globular clusters Palomar 6, Liller 1 and 47 Tuc (NGC 104). We discuss the interstellar reddening law for the HST NICMOS F110W/F160W photometric system which depends on the temperature of the source.

The Optical to Infrared Extinction Law of Magellanic Clouds Based on Red Supergiants and Classical Cepheids

open access: yesThe Astrophysical Journal, 2023
Precise interstellar dust extinction laws are important to infer the intrinsic properties of reddened objects and correctly interpret observations. In this work, we attempt to measure the optical–infrared extinction laws of the Large and Small Magellanic

A Walk through AGN Country—For the Somewhat Initiated!

open access: yesGalaxies, 2023
Key issues in AGN and galaxy formation are discussed. Very successful Unified Models explain much of the variety of AGN with orientation effects; the ingredients are shadowing by a dusty “torus” and relativistic beaming.

The peculiar extinction law of SN2014J measured with The Hubble Space Telescope [PDF]

open access: yes, 2014
The wavelength-dependence of the extinction of Type Ia SN2014J in the nearby galaxy M82 has been measured using UV to near-IR photometry obtained with the Hubble Space Telescope, the Nordic Optical Telescope, and the Mount Abu Infrared Telescope. This is

JWST’s PEARLS: Dust Attenuation and Gravitational Lensing in the Backlit-galaxy System VV 191

open access: yesThe Astronomical Journal, 2023
We derive the spatial and wavelength behavior of dust attenuation in the multiple-armed spiral galaxy VV 191b using backlighting by the superimposed elliptical system VV 191a in a pair with an exceptionally favorable geometry for this measurement ...
