Abstract

Located in southern Arizona, VERITAS is amongst the most sensitive detectors for astrophysical very high energy (VHE; E>100 GeV) gamma rays and has been operational since April 2007. We highlight some recent results from VERITAS observations. These include the long-term observations of the gamma-ray binaries HESS J0632+057 and LS I +61{\deg} 303, the observations of the Galactic Center region, and of the supernova remnant Cas~A. We discuss the results from a decade of multi-wavelength observations of the blazar 1ES 1215+303, the EHT 2017 campaign on the M87 galaxy, the discovery of 3C 264 in VHE, and the observation of three flaring quasars. Brief highlights of the indirect dark matter searches and targets-of-opportunity (ToO) observations are also discussed. The ToO observations allow for rapid follow-up of multi-messenger alerts and astrophysical transients.

Strengths

1- clearly written
2- good overview of the main recent achievements
3- cover most important science topics that can be probe by VERITAS

Weaknesses

1- A bit of perspective with respect to other IACT results may be lacking here and there.
2- A more accurate statement about the time allocated to multi-messenger and transient observations would be welcome.

Report

The present paper meets journal's acceptance criteria.

Requested changes

1 -Galactic Center : one would need to comment that high-zenith observations result in higher acceptance at the price of higher systematics too.
2- Cassiopeia A: one would expect a comment about Cas A as a potential Pevatron as SNRs are mentioned as "the most favorable sites for the acceleration of Galactic cosmic-rays up to PeV energies" above in this paragraph.
