We use a Monte Carlo radiative transfer model (MCRTM) to simulate the UBVRI light curves, images, and linear polarization of a light echo from supernova SN 1987A in the Large Magellanic Cloud (LMC) using various dust cloud shapes, sizes, and optical properties. We compare the theoretical simulations to the observations of AT 2019xis, a light echo detected at a large angular distance (4.′05) from SN 1987A. We estimate the size and optical thickness of the dust cloud based on the simulation… 

The Effects of Circumstellar Dust Scattering on the Light Curves and Polarizations of Type Ia Supernovae

Observational signatures of the circumstellar material (CSM) around Type Ia supernovae (SNe Ia) provide a unique perspective on their progenitor systems. The pre-supernova evolution of the SN



The Interstellar Light Echoes around SN 1987A

The observed light echoes around SN 1987A are modeled by dust in planar clouds roughly 120 and 330 pc in front of the supernova. The expected echo profiles depend on the observed light curve and on

The Detection of a Light Echo from the Type Ia Supernova 2006X in M100

We report the discovery of a light echo (LE) from the Type Ia supernova (SN) 2006X in the nearby galaxy M100. The presence of the LE is supported by analysis of both the Hubble Space Telescope (HST)


We present multiple-epoch measurements of the size and surface brightness of the light echoes from supernova (SN) 2014J in the nearby starburst galaxy M82. Hubble Space Telescope (HST) ACS/WFC images

Polarization of SN 1987A Revisited

The conventional picture for the origin of the polarization of a supernova is based on a model of Thomson or resonance scattering of photons traveling through an aspherical supernova atmosphere.

The Remnant of Supernova 1987A

Although it has faded by a factor of ∼107, SN 1987A is still bright enough to be observed in almost every band of the electromagnetic spectrum. Today, the bolometric luminosity of the debris is


We present the discovery of a light echo from SN 2007af, a normal Type Ia supernova (SN Ia) in NGC 5584. Hubble Space Telescope images taken three years post explosion reveal two separate echoes: an

Spectral Identification of an Ancient Supernova Using Light Echoes in the Large Magellanic Cloud

We report the successful identification of the type of the supernova (SN) responsible for the supernova remnant SNR 0509–675 in the Large Magellanic Cloud (LMC) using Gemini spectra of surrounding

On the light echo in V838 Mon

We present a theoretical outline of the light echo phenomenon and results of simple numerical simulations and we study the available images of the light echo in V838 Mon obtained with HST. An

Discovery of Optical Echoes from Supernova 1987A: New Probes of the Large Magellanic Cloud

Coronagraphic observations of SN 1987A have revealed the first light echo or transient reflection nebula due to light from an SN. Two echoes from dust 400 and 980 lt-yr in front of SN 1987A were

Infrared Emission from Interstellar Dust. II. The Diffuse Interstellar Medium

We present a quantitative model for the infrared emission from dust in the diffuse interstellar medium. The model consists of a mixture of amorphous silicate grains and carbonaceous grains, each with
