Gamma-ray Signatures of r-Process Radioactivity from the Collapse of Magnetized White Dwarfs
Tetyana Pitik, Yong-Zhong Qian, David Radice +1
We predict the gamma-ray line emission from -process nuclei synthesized in the ejecta of the accretion-induced collapse (AIC) of a magnetized, rapidly rotating white dwarf. Usin…
Collapse of Magnetized White Dwarfs as site of Heavy Element Formation and Kilonova Signal
Tetyana Pitik, David Radice, Daniel Kasen +3
We present the first end-to-end calculation connecting the accretion-induced collapse (AIC) of a magnetized, rapidly rotating white dwarf to observable kilonova signatures, combini…
Supernova production of axion-like particles coupling to electrons, reloaded
Damiano F. G. Fiorillo, Tetyana Pitik, Edoardo Vitagliano
We revisit the production of axion-like particles (ALPs) coupled to electrons at tree-level in a relativistic plasma. We explicitly demonstrate the equivalence between pseudoscalar…
Energy transfer by feebly interacting particles in supernovae: the trapping regime
Damiano F. G. Fiorillo, Tetyana Pitik, Edoardo Vitagliano
Feebly interacting particles, such as sterile neutrinos, dark photons, and axions, can be abundantly produced in the proto-neutron star (PNS) formed in core-collapse supernovae (CC…
Gamma-ray bursts and kilonovae from the accretion-induced collapse of white dwarfs
Patrick Chi-Kit Cheong, Tetyana Pitik, Luís Felipe Longo Micchi +1
We present the first seconds-long 2D general relativistic neutrino magnetohydrodynamic simulations of accretion-induced collapse (AIC) in rapidly rotating, strongly magnetized whit…
Optically Informed Searches of High-Energy Neutrinos from Interaction-Powered Supernovae
Tetyana Pitik, Irene Tamborra, Massimiliano Lincetto +1
The interaction between the ejecta of supernovae (SNe) of Type IIn and a dense circumstellar medium (CSM) can efficiently generate thermal UV/optical radiation and lead to the emis…
Exploiting stellar explosion induced by the QCD phase transition in large-scale neutrino detectors
Tetyana Pitik, Daniel Heimsoth, Anna M. Suliga +1
The centers of the core-collapse supernovae are one of the densest environments in the Universe. Under such conditions, it is conceivable that a first-order phase transition from o…
Multi-messenger detection prospects of gamma-ray burst afterglows with optical jumps
Ersilia Guarini, Irene Tamborra, Damien Bégué +2
Some afterglow light curves of gamma-ray bursts (GRBs) exhibit very complex temporal and spectral features, such as a sudden intensity jump about one hour after the prompt emission…
Is the high-energy neutrino event IceCube-200530A associated with a hydrogen-rich superluminous supernova?
Tetyana Pitik, Irene Tamborra, Charlotte R. Angus +1
The Zwicky Transient Facility (ZTF) follow-up campaign of alerts released by the IceCube Neutrino Observatory has led to the likely identification of the transient AT2019fdr as the…
Neutrino signal dependence on gamma-ray burst emission mechanism
Tetyana Pitik, Irene Tamborra, Maria Petropoulou
Long duration gamma-ray bursts (GRBs) are among the least understood astrophysical transients powering the high-energy universe. To date, various mechanisms have been proposed to e…
