Fermi-LAT Gamma-ray Emission Discovered from the Composite Supernova Remnant B0453-685 in the Large Magellanic Cloud

Jordan Eagle

A second extragalactic pulsar wind nebula (PWN) is discovered in the MeV-GeV band using the Fermi-LAT. Faint, point-like gamma-ray emission is detected at the location of the compo…

The radio emission in radio-quiet quasars: the VLBA perspective

Sina Chen, Ari Laor, Ehud Behar +2

The origin of the radio emission in radio-quiet quasars (RQQ) is not established yet. We present new VLBA observations at 1.6 and 4.9 GHz of ten RQQ (nine detected), which together…

Hard X-ray observation and multiwavelength study of the PeVatron candidate pulsar wind nebula "Dragonfly"

Jooyun Woo, Hongjun An, Joseph D. Gelfand +5

We studied the PeVatron nature of the pulsar wind nebula G75.2+0.1 ("Dragonfly") as part of our NuSTAR observational campaign of energetic PWNe. The Dragonfly is spatially coincide…

JWST constraints on the UV luminosity density at cosmic dawn: implications for 21-cm cosmology

Sultan Hassan, Christopher C. Lovell, Piero Madau +10

An unprecedented array of new observational capabilities are starting to yield key constraints on models of the epoch of first light in the Universe. In this Letter we discuss the…

Probing the History of the Galaxy Assembly of the Counter-rotating Disk Galaxy PGC 66551

Ivan Katkov, Damir Gasymov, Alexei Kniazev +4

Stellar counter-rotation in disk galaxies directly relates to the complex phenomenon of the disk mass assembly believed to be driven by external processes, such as accretion and me…
