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 […]

Why Society Needs Astronomy and Cosmology: a Gresham College Guest Lecture

A version of this post appeared on the British Council’s VOICES blog on Nov 12th 2014 Would you try and cross the South Pole wearing only flip-flops? Or row across the Atlantic on an inflatable swimming pool? Or describe the beauty and mystery of the Universe using only the most common 1,000 words in English? As a […]

g-ASTRONOMY: The cosmos at the tip of your tongue

Posted on Sep 20, 2016 in g-ASTRONOMY, Outreach, Public lecture, Science, universe

Astrophysics provides us with an exciting, engaging way to talk about the science of the cosmos and its importance for society. Posted on the IOP blog on Sept 20th 2016 Interest for astronomy and astrophysics is also one of the most-often cited reasons by students taking up physics at undergraduate level. But by its nature […]

Is Alice really burning?

Posted on Jun 5, 2014 in Outreach, quantum mechanics, universe

Imperial Physics had the somewhat unexpected pleasure to welcome Caltech theoretical physicist Sean Carroll (of fame) and science writer Jennifer Ouellette (whom the Twitterati might know under her Twitter name-de-plume of @JenLucPiquant), who were in London after participating to the Cheltenham Science Festival. They joined forces and gave an inspirational public talk entitled “Alice is burning”. […]
