Pulsar wind nebula DA495 examined in TeV gamma-rays and with broadband spectral modeling
Abstract
We present observations from the Very Energetic Radiation Imaging Telescope Array System (VERITAS) gamma-ray observatory and the Nuclear Spectroscopic Telescope Array (NuSTAR) hard X-ray observatory of pulsar wind nebula (PWN) DA 495, which was recently found to be a gamma-ray source by the High Altitude Water Cherenkov observatory (HAWC). DA 495 is an aged PWN, previously identified in radio and X-ray, with unusually strong magnetic fields. Broadband spectral modeling, which now includes spectral information in hard X-rays and TeV gamma-rays, can place constraints on the properties of the particle population in this PWN and allows for both leptonic and hadronic emission scenarios to be evaluated. In this dissertation talk, I will discuss the results from the recent observations and present the subsequent multiwavelengh modeling study.
