An Extreme Scattering Event Toward PSR J2313+4253
Zachary C. Zelensky, Jacob E. Turner, Juan G. Lebron Medina +7
We present evidence of an extreme scattering event (ESE) toward PSR J2313+4253 using high-cadence observations taken with the Green Bank Observatory 20m telescope. The high density…
Constraining Lens Masses in Moderately to Highly Magnified Microlensing Events from Gaia
U. Pylypenko, Å. Wyrzykowski, P. J. MikoÅajczyk +57
Microlensing events provide a unique way to detect and measure the masses of isolated, non-luminous objects, particularly dark stellar remnants. Under certain conditions, it is pos…
The origin and evolution of the normal Type Ia SN 2018aoz with infant-phase reddening and excess emission
Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +40
SN~2018aoz is a Type Ia SN with a -band plateau and excess emission in the infant-phase light curves 1 day after first light, evidencing an over-density of surface ir…
Follow-up on three poorly studied AM CVn stars
Amornrat Aungwerojwit, Boris T. Gaensicke, E. Breedt +12
We report follow-up observations of three poorly studied AM CVn-type binaries: CRTS CSS150211 J091017-200813, NSV1440, and SDSSJ183131.63+420220.2. Analysing time-series photometry…

Daniel E. Reichart
Here we briefly describe each of the modules that constitute Skynet's new "Astrophotography of the Multi-Wavelength Universe!", or MWU!, curriculum.
The Pulsar Science Collaboratory: Multi-Epoch Scintillation Studies of Pulsars
Jacob E. Turner, Juan G. Lebron Medina, Zachary Zelensky +13
We report on findings from scintillation analyses using high-cadence observations of eight canonical pulsars with observing baselines ranging from one to three years. We obtain sci…
