Contrastive Learning for Interpretable Anomaly Detection at Collider Experiments
Haoyi Jia, Sagar Addepalli, Julia Gonski
Generic event-level anomaly detection for collider physics has two recurring problems: anomaly scores are hard to interpret, and they correlate strongly with energy scale and objec…
A new likely pulsar binary in 47~Tucanae from continuum searches
Thomas J. Maccarone, Alessandro Paduano, Arash Bahramian +6
We present evidence that the X-ray source 47~Tuc~W41, long considered to be an X-ray source powered by coronal activity, is actually a redback pulsar binary. The source continually…
Long-period radio transient PSR J0901-4046 is not an Isolated White Dwarf Pulsar
Maxim Lyutikov, Mukremin Kilic, Alexander Wolszczan +1
We report the {\it Chandra} non-detection of PSR J09014046, a seconds long-period radio transient (LPT). For a distance of 467 pc, the upper limit on X-ray luminosity…
A pulsar escaping an ancient open cluster via tidal stripping
Lei Zhang, Xiaoting Fu, Di Li +21
Open clusters are the primary birthplaces of stars in the Milky Way disk, yet their neutron star progeny are rarely found within them, presumably due to supernova-induced kicks tha…
The one and the only: the pulsar - white dwarf system in NGC 6749
Paulo C. C. Freire, Yinfeng Dai, Mario Cadelano +7
PSR J1905+0154A is a binary millisecond pulsar located in the globular cluster (GC) NGC 6749. It was discovered in 2004 in a search for pulsars in GCs carried out with the Arecibo…
A broadband search for coherent radio emission in cataclysmic variables
Margaret E. Ridder, Paul E. Barrett, Craig O. Heinke +1
Radio observations of cataclysmic variables have revealed a variety of behavior. From some systems, we see bright unpolarized radio flares occurring during dwarf nova outbursts, co…
