2013-Apr-18: A new lower limit to the redshift of the PKS 1424+240 has been published (arXiv:1304.4859). PKS1424+240 was discovered in the VHE band by VERITAS and this new limit makes it the most distant VHE-detected blazar ever, with potential implications for the measurement of the gamma-ray opacity at VHE energies. See the UCSC press release here.

 


 

2013-Oct-26: The VHE gamma-ray community celebrates Trevor Weekes at TrevorFest. See details here. The slides of the talks are posted here - a great overview of some of the early history of the VHE gamma-ray field!


The VERITAS team and the Fermi Science Support Center are pleased to announce a pilot program for the Fermi Cycle 8 GI Program that supports collaborative efforts to jointly observe high-energy gamma-ray sources with VERITAS and Fermi.  Successful proposals will be selected on a competitive basis via the Fermi Cycle 8 proposal review.  Details of the program are described in the VERITAS-Fermi Collaborative Agreement.  Further information is available at the FSSC website.

 

2013-Apr-13: VERITAS and MAGIC report dramatic flaring activity from Mrk421 in Very-High-Energy gamma rays, in  The Astronomers' Telegram #4976, here .

 


VERITAS and the entire VHE community were saddened by the loss of Alex "Sasha" Konopelko on August 10, 2012. Sasha was one of the key investigators in the HEGRA collaboration early in his career. He contributed, through his skills simulating air showers and their detection by air Cherenkov telescopes, to the design of the HEGRA system. He also was a pioneer in the stereo analysis techniques that ultimately led to the third generation of VHE telescope arrays. The success of the HEGRA system and the validation of the stereoscopic technique was in large part due to Sasha's insightful contributions. Sasha took his talents to the HESS collaboration and subsequently to the VERITAS collaboration where the analysis methods he helped develop have become the backbone of the field. The success of the field of ground based gamma-ray astronomy over the past decade owes no small measure of thanks to Sasha. Sasha was most recently a member of the VERITAS collaboration and also the CTA-US effort. His colleagues in those collaborations have been the most recent beneficiaries of his talent and expertise in the field of VHE gamma-ray astronomy. Sasha's talents and skills will be missed by all and his infectious sense of humor will be memories we will all cherish.
