VERITAS follow-up observations of GRBs detected by Fermi and Swift — •Christian Skole — DESY, Platanenallee 6, 15738 Zeuthen

The VERITAS experiment is a ground based Cherenkov telescope array located in southern Arizona, USA. Its purpose is the measurement of very high energetic gamma-rays with a maximum sensitivity ranging from 100 GeV to 10 TeV.

As many theoretical models predict, gamma-ray bursts (GRBs) and their afterglows should be able to emit photons in this energy range. To gain better understanding of the processes that lead to those short intensive outbursts an important point of the VERITAS observing plan is the rapid follow-ups of GRBs detected by satellite experiments like Fermi and Swift.

In this study we will present the upper limits of several GRBs measured with VERITAS during the past observing seasons.
