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.
List of changes
Requested changes are implemented as per the referee's comments as follows:
1. "and increased in the systematic" added for the higher zenith observation of Galactic Centre region section (page 3, last paragraph)
2." Cassiopeia A is a potential PeVatron candidate" added in the Cassiopeia A section (page 4, first paragraph)
3. VERITAS Multi-messenger and transient observations are proposal driven, so there is no fixed time allocated for such observation. The sentence is rephrased accordingly to suggest this. (page 5, last paragraph)
