Today on the arXiv: Light echo gives insight into SNIa dust environment

Posted on Oct 12, 2016 in astro-ph, Research, universe

I noticed this interesting paper using high resolution, multi-epoch images from Hubble to study the time evolution of the aftermath of the explosion of SNIa SN204J, which went off in 2014 in the nearby galaxy M82 (a mere 11 million light years away). The data show the presence of a radially expanding light echo, as well […]

Today on the arXiv: Prospector-alpha opens the way to high-accuracy photometry-based estimation of galactic properties

Posted on Sep 30, 2016 in astro-ph, Research, Science, universe

There is a terrific paper on today’s arXiv: The Prospector-alpha code is an impressive new approach to estimating a large number of important physical parameters of galaxies, including indicators for the galaxy’s star formation history, its metallicity, its mass and dust content. The code contains a large number of free physical parameters (describing star formation […]
