    A rapid response to GRB 070411
    We report on early observations of the optical afterglow of GRB 070411 obtained by the Črni Vrh 0.6-m, the ROTSE IIIc 0.45-m, and the Tautenburg 1.34-m Schmidt...

    Catalog of Long-term Transient Sources in the First 10 yr of Fermi-LAT Data
    We present the first Fermi Large Area Telescope (LAT) catalog of long-term γ-ray transient sources (1FLT). This comprises sources that were detected on monthly...

    Changing Look of the Optical Spectrum of the MeV Blazar PKS 0446+112 (4FGL J0449.1+1121)
    Following the high activity of the γ-ray Fermi source 4FGL J0449.1+1121 (PKS 0446+112), possibly associated with a IceCube neutrino event IC-240105A, we...

    Constraints on Gamma-Ray and Neutrino Emission from NGC 1068 with the MAGIC Telescopes
    Starburst galaxies and star-forming active galactic nuclei are among the candidate sources thought to contribute appreciably to the extragalactic gamma-ray and...

    Dark bursts in the Swift era
    The nature of the dark bursts is still not fully understood. Here, we report on some of our recent studies on Swift dark bursts. Thereby, we pay particular...

    Discovery of a Gamma-Ray Black Widow Pulsar by GPU-accelerated Einstein@Home
    We report the discovery of 1.97 ms period gamma-ray pulsations from the 75 minute orbital-period binary pulsar now named PSR J1653-0158. The associated Fermi...

    Galactic population of radio and gamma-ray pulsars
    We simulate the characteristics of the Galactic population of radio and gamma-ray pulsars using Monte Carlo techniques. At birth, neutron stars are spatially...
