Swift Follow-Up of Reported Radio Pulsars at Fermi 4FGL Unassociated Sources
Stephen Kerby, Abraham D. Falcone, Paul S. Ray
Following the discovery of radio pulsars at the position of Fermi-LAT unassociated sources by the TRAPUM group, we conduct Swift-XRT observations of six of those 4FGL sources to de…
Testing the Blazar Sequence with Spectra of Recently Discovered Dim Blazars from the Fermi Unassociated Catalog
Stephen Kerby, Abraham D. Falcone
Recent works have developed samples of blazars from among the Fermi-LAT unassociated sources via machine learning comparisons with known blazar samples. Continued analysis of these…
Using Neural Networks to Differentiate Newly Discovered BL Lacs and FSRQs among the 4FGL Unassociated Sources Employing Gamma-ray, X-ray, UV/Optical and IR Data
Amanpreet Kaur, Stephen Kerby, Abraham D. Falcone
Among the ~2157 unassociated sources in the third data release (DR3) of the fourth Fermi catalog, ~1200 were observed with the Neil Gehrels Swift Observatory pointed instruments. T…
A Search for Radio Technosignatures at the Solar Gravitational Lens Targeting Alpha Centauri
Nick Tusay, Macy J. Huston, Cayla M. Dedrick +17
Stars provide an enormous gain for interstellar communications at their gravitational focus, perhaps as part of an interstellar network. If the Sun is part of such a network, there…
Probing the origin of 4FGL J0822.8-4207: cosmic ray illumination from the SNR Puppis A and the Herbig-Haro object HH219
Miguel Araya, Luis Gutiérrez, Stephen Kerby
4FGL J0822.8-4207 is a point source found in the 4FGL-DR2 catalog by the gamma-ray observatory Fermi-LAT and has no known association. We carry out X-ray observations of 4FGL J0822…
Multiwavelength Spectral Analysis and Neural Network Classification of Counterparts to 4FGL Unassociated Sources
Stephen Kerby, Amanpreet Kaur, Abraham D. Falcone +7
The Fermi-LAT unassociated sources represent some of the most enigmatic gamma-ray sources in the sky. Observations with the Swift-XRT and -UVOT telescopes have identified hundreds…
Stellar Gravitational Lens Engineering for Interstellar Communication and Artifact SETI
Stephen Kerby, Jason T. Wright
Several recent works have proposed "stellar relay" transmission systems in which a spacecraft at the focus of a star's gravitational lens achieves dramatic boosts in the gain of an…
X-ray Spectra and Multiwavelength Machine Learning Classification for Likely Counterparts to Fermi 3FGL Unassociated Sources
Stephen Kerby, Amanpreet Kaur, Abraham D. Falcone +4
We conduct X-ray spectral fits on 184 likely counterparts to Fermi-LAT 3FGL unassociated sources. Characterization and classification of these sources allows for more complete popu…
On the prospect of using the maximum circular velocity of halos to encapsulate assembly bias in the galaxy-halo connection
Idit Zehavi, Stephen E. Kerby, Sergio Contreras +3
We investigate a conceptual modification of the halo occupation distribution approach, using the halos' present-day maximal circular velocity, $\vmax$, as an alternative to halo ma…
