Abstract

We have entered a golden age for studying astrophysical “transients” (short and violent astrophysical events). Recent advances in the field of large-scale, high-cadence astronomical surveys have provided unprecedentedly rich and diverse data sets and transient astronomy is said to have entered a “big data era”. I will give a short overview of several on-going and future instruments which are real « game-changers » in the field and will show how combining their assets, as well as using tools from  "data science" - involving high-performance computing and data mining - can lead to promising new science. I will then share recent results from the first UV survey of the early evolution of interacting supernovae and from mining twenty years of X-ray archival data in search for the shortest transients, including the elusive signatures of the mysterious supernova "shock breakout".

 

Note the unusual date/time (Wednesday morning). 

The seminar will be hosted on Zoom: https://zoom.us/j/9290951953
