Fermi-LAT detections of novae V1723 Sco and V6598 Sgr
P. Fauverge, P. Jean, K. Sokolovsky +8
Context. Numerous classical novae have been observed to emit γ-rays (E > 100 MeV) detected by the Fermi-LAT. The prevailing hypothesis attributes this emission to the interaction o…
Multiple outflows and delayed ejections revealed by early imaging of novae
Elias Aydi, John D. Monnier, Antoine Mérand +39
Novae are thermonuclear eruptions on accreting white dwarfs in interacting binaries. Although most of the accreted envelope is expelled, the mechanism -- impulsive ejection, multip…
What determines the -ray luminosities of classical novae?
Peter Craig, Elias Aydi, Laura Chomiuk +25
Classical novae in the Milky Way have now been well-established as high-energy GeV -ray sources. In novae with main-sequence companions, this emission is believed to result from…
The Symbiotic Recurrent Nova V745 Sco at Radio Wavelengths
Isabella Molina, Laura Chomiuk, Justin D. Linford +14
V745 Sco is a Galactic symbiotic recurrent nova with nova eruptions in 1937, 1989 and 2014. We study the behavior of V745 Sco at radio wavelengths (0.6-37,GHz), covering both its 1…
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…
The multi-wavelength view of shocks in the fastest nova V1674 Her
K. V. Sokolovsky, T. J. Johnson, S. Buson +41
Classical novae are shock-powered multi-wavelength transients triggered by a thermonuclear runaway on an accreting white dwarf. V1674 Her is the fastest nova ever recorded (time to…
Synchrotron emission from double-peaked radio light curves of the symbiotic recurrent nova V3890 Sagitarii
Miriam M. Nyamai, Justin D. Linford, James R. Allison +4
We present radio observations of the symbiotic recurrent nova V3890 Sagitarii following the 2019 August eruption obtained with the MeerKAT radio telescope at 1.28 GHz and Karl G. J…
The first nova eruption in a novalike variable: YZ Ret as seen in X-rays and gamma-rays
Kirill V. Sokolovsky, Kwan-Lok Li, Raimundo Lopes de Oliveira +16
Peaking at 3.7 mag on 2020 July 11, YZ Ret was the second-brightest nova of the decade. The nova's moderate proximity (2.7 kpc from Gaia) provided an opportunity to explore its mul…
Classical Novae at Radio Wavelengths
Laura Chomiuk, Justin D. Linford, Elias Aydi +20
We present radio observations (1--40 GHz) for 36 classical novae, representing data from over five decades compiled from the literature, telescope archives, and our own programs. O…
Shocks and dust formation in nova V809 Cep
Aliya-Nur Babul, Jennifer L. Sokoloski, Laura Chomiuk +5
The discovery that many classical novae produce detectable GeV -ray emission has raised the question of the role of shocks in nova eruptions. Here we use radio observations of n…

We present X-ray and radio observations of what may be the closest type Iax supernova (SN) to date, SN 2014dt (d=12.3-19.3 Mpc) and provide tight constraints on the radio and X-ray…
Rapid Spectral Variability of a Giant Flare from a Magnetar in NGC 253
