We present a new technique to infer dust locations towards reddened Type Ia supernovae and to help discriminate between an interstellar and a circumstellar origin for the observed extinction. Using ...

Shedding light on the Type Ia supernova extinction puzzle: dust location found
The colour evolution of reddened Type Ia supernovae can place strong constraints on the location of dust and help address the question of whether the observed extinction stems from the interstellar
The Circumstellar Environment of Type Ia Supernovae
Type Ia supernovae (SNe Ia) have proven to be extremely useful for measuring cosmological distances and were used for the discovery of the accelerated expansion of the universe. Although thousands ...
Mapping Circumstellar Matter with Polarized Light: The Case of Supernova 2014J in M82
Optical polarimetry is an effective way of probing the environment of a supernova for dust. We acquired linear HST ACS/WFC polarimetry in bands , , and of the supernova (SN) 2014J in M82 at six
The Cold and Dusty Circumstellar Matter around Fast-expanding Type Ia Supernovae
SNe Ia play key roles in revealing the accelerating expansion of the universe, but our knowledge of their progenitors is still very limited. Here we report the discovery of a rigid dichotomy in
A Dynamical Constraint on Interstellar Dust Models from Radiative Torque Disruption
Interstellar dust is an essential component of the interstellar medium (ISM) and plays critical roles in astrophysics. Achieving an accurate model of interstellar dust is therefore of great
iPTF Survey for Cool Transients
We performed a wide-area (2000 deg2) g and I band experiment as part of a two month extension to the Intermediate Palomar Transient Factory. We discovered 36 extragalactic transients including
No Evidence of Circumstellar Gas Surrounding Type Ia Supernova SN 2017cbv
Nearby type Ia supernovae (SNe Ia), such as SN 2017cbv, are useful events to address the question of what the elusive progenitor systems of the explosions are. Hosseinzadeh et al. suggested that the
Nebular spectroscopy of SN 2014J: Detection of stable nickel in near-infrared spectra
We present near-infrared (NIR) spectroscopy of the nearby supernova 2014J obtained ∼450 d after explosion. We detect the [Ni II] 1.939 μm line in the spectra indicating the presence of stable 58Ni in
iPTF16abc and the population of Type Ia supernovae: comparing the photospheric, transitional, and nebular phases
Key information about the progenitor system and the explosion mechanism of Type Ia supernovae (SNe Ia) can be obtained from early observations, within a few days from explosion. iPTF16abc was
Time-varying Extinction, Polarization, and Colors of Type Ia Supernovae due to Rotational Disruption of Dust Grains
Observations toward type Ia supernovae (SNe Ia) frequently report an unusually low total-to-selective extinction ratio (RV < 2) and a small peak wavelength of polarization (λmax < 0.4 μm). Hoang et


Dust around Type Ia Supernovae
An explanation is given of the low value of Rλ ≡ Aλ/E(B - V), the ratio of absolute to selective extinction deduced from Type Ia supernova observations. The idea involves scattering by dust clouds
Anomalous extinction behaviour towards the Type Ia SN 2003cg
We present optical and near-infrared photometry and spectroscopy of the Type Ia SN 2003cg, which exploded in the nearby galaxy NGC 3169. The observations cover a period between -8.5 and +414 days
Herschel limits on far-infrared emission from circumstellar dust around three nearby type Ia supernovae.
The use of Type Ia supernovae (SNe Ia) as distance indicators is essential for studying the expansion history of the Universe and for exploring the nature of dark energy. However, a lack of
Detection of Circumstellar Material in a Normal Type Ia Supernova
The spectroscopic detection of circumstellar material in a normal type Ia supernova explosion indicates that this material was ejected from the progenitor system.
The reddening-free decline rate versus luminosity relationship for type ia supernovae
We develop a method for estimating the host galaxy dust extinction for type Ia supernovae based on an observational coincidence first noted by Lira, who found that the B-V evolution during the period
SN 2002cv: a heavily obscured Type Ia supernova
We present V RIJHK photometry, and optical and near-infrared spectroscopy, of the heavily extinguished Type Ia supernova (SN) 2002cv, located in NGC 3190, which is also the parent galaxy of the Type
Properties and Alignment of Interstellar Dust Grains toward Type Ia Supernovae with Anomalous Polarization Curves
Recent photometric and polarimetric observations of Type Ia supernovae (SNe Ia) show unusually low total-to-selective extinction ratios (RV < 2) and wavelengths of maximum polarization (λmax < 0.4
Circumstellar Na I and Ca II absorption lines of type Ia supernovae in the symbiotic scenario
The formation of circumstellar Na I and Ca II resonance absorption lines in a type Ia supernova is studied in the case where the supernova explodes in a binary system with a red giant. The model
Properties of extragalactic dust inferred from linear polarimetry of Type Ia Supernovae
Aims. The aim of this paper is twofold: 1) to investigate the properties of extragalactic dust and compare them to what is seen in the Galaxy; 2) to address in an independent way the problem of the
We use a sample of 121 spectroscopically normal Type Ia supernovae (SNe Ia) to show that their intrinsic color is correlated with their ejecta velocity, as measured from the blueshift of the Si ii
