The Third Fermi Large Area Telescope Catalog of Gamma-Ray Pulsars

open access: yesThe Astrophysical Journal, 2023
We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio searches of LAT sources will likely reveal pulsations once phase-connected

Incremental Fermi Large Area Telescope Fourth Source Catalog [PDF]

open access: yesAstrophysical Journal Supplement Series, 2022
We present an incremental version (4FGL-DR3, for Data Release 3) of the fourth Fermi Large Area Telescope (LAT) catalog of γ-ray sources. Based on the first 12 years of science data in the energy range from 50 MeV to 1 TeV, it contains 6658 sources.

The Ultimately Large Telescope: What Kind of Facility Do We Need to Detect Population III Stars? [PDF]

open access: yesAstrophysical Journal, 2020
The launch of the James Webb Space Telescope (JWST) will open up a new window for observations at the highest redshifts, reaching out to . However, even with this new facility, the first stars will remain out of reach, as they are born in small minihalos
