Realtime Astroparticle Physics

Mission: In the last few years, large neutrino, gamma or gravitational wave telescopes have established dedicated, near realtime follow-up observations using a range of astronomical telescopes. Such follow-up observation provide a significant increase of sensitivity to astrophysical transients, such as Gamma Ray Bursts, Supernovae or Active Galactic Nuclei by complementing the neutrino/gamma/gravitational wave signal with an electromagnetic signal from optical wide field imagers and X-ray telescopes. The first workshop on this emerging field of realtime astroparticle physics will focus on the science that is achievable with such programs, the methods that are being developed as well as the infrastructure (network of telescopes, etc) that are either available or desired for such programs.

17:10 Radio transient searches

I will review the various methods that have been used in the search for transient radio signals. After introducing the so-called "transient phase space", I will present the highlights of the discoveries from the past few years. Then, I shall focus on a number of as-yet-unexplained signals which might prove to be powerful cosmological probes. Next, I will review the known sources of transient radio emission, as well as speculating on theoretical possibilities, considering the observational evidence for these. I will conclude by looking at the very latest in search techniques as the community transitions from archival searches of single-telescope surveys towards real-time all-sky monitoring using vast telescope arrays.

17:40 Radio transients in the High Time Resolution Universe radio survey

We are carrying out the most ambitious and comprehensive all-sky survey for pulsars and transient sources to date. Using new digital filterbank backends this survey will create a digital record of the sky that can be data mined in the future and used to search for relativistic binary and millisecond pulsars, RRATs, and extragalactic radio bursts. Using GPU technology we have developed a realtime transient detector capable of finding intermittent pulsars and fast radio bursts within minutes of the data being taken. The first results of this transient search will be presented.

09:35 FRAM -- The Robotic Telescope in the Pierre Auger Observatory

F/(Ph)otometric Robotic Atmospheric Monitor is one of the atmospheric monitoring instruments at the Pierre Auger Observatory in Argentina. FRAM is an optical telescope equipped with CCD cameras and it automatically observes a set of selected standard stars. FRAM observations are used to obtain the wavelength dependence of the light extinction. FRAM telescope is also able to observe secondary astronomical targets, and namely the detection of optical counterparts of gamma-ray bursts has already proven to be successful. Finally, a wide-field CCD camera of FRAM can be used for rapid monitoring of atmospheric conditions along the track of particularly interesting cosmic ray showers.

10:00 Gamma-ray Observations of Pulsars with the Fermi LAT

The Large Area Telescope (LAT) on the Fermi satellite has opened a new era in the study of pulsars, by increasing the population of known gamma-ray pulsars from fewer than 10 to more than 120 objects, thereby establishing pulsars as the dominant class of GeV sources in the Galaxy. The improved sensitivity of the LAT has allowed studies of the light curves and spectra of gamma-ray pulsars with unprecedented details, and the discovery of new populations of radio quiet pulsars and millisecond pulsars in Fermi unidentified sources has revolutionized our view of the gamma-ray pulsar population. I will review Fermi LAT observations of pulsars after four years of mission, describe the techniques used to detect pulsars in the LAT data and highlight some of the exciting results.

11:45 Revealing deaths of massive stars with high-energy neutrinos

Neutrinos play important roles in revealing mechanisms of energetic astrophysical explosions such as gamma-ray bursts (GRBs) and supernovae (SNe). The large neutrino detector, IceCube has opened a new window of the multi-messenger astronomy. I overview theoretical prospects of high-energy higneutrino emissions from gamma-ray bursts, newly-born magnetars and luminous supernovae in view of the latest theoretical and observational developments, and discuss the potential of GeV-TeV neutrinos for revealing the progenitor star, circumstellar environment and the connection between GRBs and SNe.

14:45 Ground-based gravitational wave detectors and their capabilities through 2020

In this talk I describe the advanced ground-based gravitational-wave detector projects (LIGO in the USA, VIRGO in Italy, GEO in Germany, KAGRA in Japan, LIGO in India), review their status and capabilities, and outline the different signal analysis methods and pipelines that are used. We expect that the first direct detections of gravitational waves (perhaps around 2017) will be from the coalescence and merger of binary neutron star pairs. Such events may also be accompanied by electromagnetic gamma-ray bursts.
