EMU discovery of Thunder: a bow-shock PWN powered by PSR J1631-4722 escaping Nimbus SNR (G336.7+0.5)
S. LazareviÄ, C. Maitra, A. Ahmad +21
We report the discovery of a bow-shock pulsar wind nebula (PWN), dubbed Thunder, powered by the radio pulsar PSR J1631-4722 and projected within the Galactic supernova remnant (SNR…
A Multiwavelength Interpretation of HESS J1857+026 Emission Using the Fermi-LAT, VERITAS, and HAWC Observatories
Jordan Eagle, Yu Chen, Ramiro Torres-Escobedo +2
We present a new study on the MeV-TeV gamma-ray origin of HESS J1857+026 using data collected from the Fermi-LAT, VERITAS, and HAWC observatories. A spatial and spectral study of H…
Evidence of an Energetic Magnetar Powering 1LHAASO J05004454
J. A. J. Alford, J. D. Gelfand, M. Abdelmaguid +1
We investigate the origin of unidentified, extended TeV source 1LHAASO J05004454, considering three possible origins: cosmic rays interacting with a molecular cloud (MC), partic…
HI Observations of Giant Low Surface Brightness Galaxies
Philip Lah, Nikhil Arora, Ivan Yu. Katko +5
Giant low surface brightness galaxies (gLSBs) are galaxies with extremely extended, faint, optical disks over 50 kpc in radius and have high total masses which can reach 10^12 sola…
Danger Zone: Establishing Buffers for Enhanced Classification in BPT Diagrams
Changhyun Cho, Ahmad Nemer, Ivan Yu. Katkov +1
This study utilizes unsupervised machine learning, specifically the uniform manifold approximation and projection (UMAP) algorithm, to classify optical spectra originating from sta…
Low-energy Radio Bursts from Magnetar XTE J1810197: Implications for Fast Radio Bursts
Banshi Lal, Yogesh Maan, Moaz Abdelmaguid +3
Magnetars are the leading candidate sources of fast radio bursts (FRBs). However, the observational probes of the connections between magnetars and FRBs are severely limited by the…
