Locating Astrophysical Transients

New generation wide-field instruments, especially SKA pathfinders in the radio regime, will detect a huge number of transient sources that can be followed-up by very long baseline interferometry (VLBI) at the highest possible angular resolution. Finding and localization of these, as well as discussing the science case and realization of high resolution observations in multi-wavelength transient projects, is the main focus of the workshop. The science topics covered will be Galactic neutron stars (pulsars) and black holes, gamma-ray binaries, unidentified TeV sources, novae, supernovae, GRB, tidal disruption events and astrophysical sources of gravitational waves. The instruments and techniques to be introduced are the European VLBI Network (EVN), real-time e-VLBI, WSRT Apertif, SKA pathfinders (e-Merlin/LOFAR/ASKAP/MeerkAT/MWA/LWA) as well as transient facilities and programmes in the other parts of the electromagnetic spectrum.

Our main aims are to have both students and experienced researchers, from both the wide-field and the VLBI communities: 1) learn practical hands-on methods from each other’s fields in “school” fashion, 2) form the new collaborations needed to make this new connection of fields a success. Furthermore, by offering a scientific program of excellent confirmed speakers from across the electromagnetic and gravity-wave spectrum, we, introduce VLBI to a wider, non-radio astronomy transient community. We expect to strengthen the scientific case for a long-baseline configuration SKA as well.

SnowPAC 2013 — Black Hole Fingerprints: Dynamics, Disruptions & Demographics

The 5th annual Snowbird Workshop on Particle Astrophysics, Astronomy, and Cosmology (SnowPAC) will be held from 17-23 March 2013 at the Cliff Lodge at Snowbird Ski Resort in Little Cottonwood Canyon, Utah, USA. The conference will focus on the interaction of massive black holes with the stars around them, and our ability to use stellar dynamics and tidal disruption events to understand the demographics of massive black holes. We will cover the following broad topics:

– Supermassive black hole demographics & formation
– Tidal disruption observations, signatures & rates
– Nuclear star clusters & the dynamics of dense stellar systems
– Hypervelocity stars
– Black holes in star clusters & intermediate mass black holes
