Three New Likely Spider Millisecond Pulsar Binaries and Optical Kinematic Tracers of Intrabinary Shocks
Jay Strader, Rebecca Kyer, Laura Chomiuk +9
We report the discovery of three candidate spider millisecond pulsars via multi-wavelength follow-up of unassociated Fermi Large Area Telescope gamma-ray sources. All have optical…
Observational Astrophysics Research through Cross Institutional Research Partnerships
Kristen C. Dage, Linda Strubbe, Rhianna Taub +16
Undergraduate research in STEM can be a transformative experience, especially for Community College students, many of whom come from under-represented backgrounds. However, undergr…
Classifying Compact Radio Emission in Nearby Galaxies: a 10GHz Study of Active Galactic Nuclei, Supernovae, Anomalous Microwave Emission and Star Forming Regions
Kristen C. Dage, Eric W. Koch, Evangelia Tremou +19
We present 115 compact radio point sources in three galaxies, NGC 5474, NGC 4631 and M51, taken in the most extended (A-)configuration of the Karl G. Jansky Very Large Array at 10G…
Radio Continuum Studies of Ultra-Compact and Short Orbital Period X-Ray Binaries
Kristen C. Dage, Teresa Panurach, Kwangmin Oh +14
We present the radio continuum counterparts to the enigmatic ultra-compact X-ray binaries (UCXBs); a black hole or neutron star accreting from a hydrogen-deficient white dwarf dono…
PSR J1947-1120: A New Huntsman Millisecond Pulsar Binary
Jay Strader, Paul S. Ray, Ryan Urquhart +11
We present the discovery of PSR J1947-1120, a new huntsman millisecond pulsar with a red giant companion star in a 10.3 d orbit. This pulsar was found via optical, X-ray, and radio…
Detecting the Black Hole Candidate Population in M51's Young Massive Star Clusters: Constraints on Accreting Intermediate Mass Black Holes
Kristen C. Dage, Evangelia Tremou, Bolivia Cuevas Otahola +24
Intermediate mass black holes (10^2 < M_BH< 10^5 Msun) are an open question in our understanding of black hole evolution and growth. They have long been linked to dense star cluste…
Do Neutron Star Ultra-Luminous X-Ray Sources Masquerade as Intermediate Mass Black Holes in Radio and X-Ray?
Teresa Panurach, Kristen C. Dage, Ryan Urquhart +8
Ultraluminous X-ray sources (ULXs) were once largely believed to be powered by super-Eddington accretion onto stellar-mass black holes, although in some rare cases, ULXs also serve…
A Survey for Radio Emission from White Dwarfs in the VLA Sky Survey
Ingrid Pelisoli, Laura Chomiuk, Jay Strader +22
Radio emission has been detected from tens of white dwarfs, in particular in accreting systems. Additionally, radio emission has been predicted as a possible outcome of a planetary…
Revisiting the classics: On the evolutionary origin of the "Fe II" and "He/N" spectral classes of novae
E. Aydi, L. Chomiuk, J. Strader +21
The optical spectra of novae are characterized by emission lines from the hydrogen Balmer series and either Fe II or He/N, leading to their traditional classification into two spec…
Catching a nova X-ray/UV flash in the visible? Early spectroscopy of the extremely slow Nova Velorum 2022 (Gaia22alz)
E. Aydi, L. Chomiuk, J. Mikołajewska +22
We present early spectral observations of the very slow Galactic nova Gaia22alz, over its gradual rise to peak brightness that lasted 180 days. During the first 50 days, when the n…
Tracking the Enigmatic Globular Cluster Ultracompact X-ray Binary X1850--087: Extreme Radio Variability in the Hard State
T. Panurach, R. Urquhart, J. Strader +6
The conditions under which accreting neutron stars launch radio-emitting jets and/or outflows are still poorly understood. The ultracompact X-ray binary X1850--087, located in the…
Multi-Wavelength Observations Of A New Redback Millisecond Pulsar 4FGL J1910.7-5320
Ka-Yui Au, Jay Strader, Samuel J. Swihart +9
We present the study of multi-wavelength observations of an unidentified Fermi Large Area Telescope (LAT) source, 4FGL J1910.7-5320, a new candidate redback millisecond pulsar bina…
The MAVERIC Survey: Variable Jet-Accretion Coupling in Luminous Accreting Neutron Stars in Galactic Globular Clusters
T. Panurach, J. Strader, A. Bahramian +9
Accreting neutron stars in low-mass X-ray binaries show outflows -- and sometimes jets -- in the general manner of accreting black holes. However, the quantitative link between the…
GS 2000+25: The Least Luminous Black Hole X-ray Binary
J. Rodriguez, R. Urquhart, R. M. Plotkin +6
Little is known about the properties of the accretion flows and jets of the lowest-luminosity quiescent black holes. We report new, strictly simultaneous radio and X-ray observatio…
