Extreme Stellar Death and Galaxy Feedback at z = 2: A Rest-frame Ultraviolet Characterization of the Strongly Lensed Superluminous Supernova 2025wny
Willem B. Hoogendam, David O. Jones, Christopher J. Storfer +26
We present photometric and spectroscopic follow-up observations of the strongly-lensed H-poor superluminous supernova (SLSN) 2025wny at . We use integral-field Keck-II/…
From the Milky Way to the Early Universe: How Metallicity Shapes the Formation of Double Neutron Stars
Abhishek Chattaraj, Jeff J. Andrews, Monica Gallegos-Garcia +10
Among the compact binaries detected through gravitational wave (GW) emission, double neutron stars (DNSs) hold the unique distinction of having well-characterized local analogs in…
Three dimensional magnetorotational core-collapse supernova explosions of a 39 solar mass progenitor star
Jade Powell, Bernhard Mueller, David R. Aguilera-Dena +1
We perform three-dimensional simulations of magnetorotational supernovae using a progenitor star with two different initial magnetic field strengths of G…
Density Profiles of Collapsed Rotating Massive Stars Favor Long Gamma-Ray Bursts
Goni Halevi, Belinda Wu, Philipp Moesta +3
Long-duration gamma-ray bursts (lGRBs) originate in relativistic collimated outflows -- jets -- that drill their way out of collapsing massive stars. Accurately modeling this proce…
A synthetic population of Wolf-Rayet stars in the LMC based on detailed single and binary star evolution models
D. Pauli, N. Langer, D. R. Aguilera-Dena +2
Without doubt, mass transfer in close binary systems contributes to the populations of Wolf-Rayet (WR) stars in the Milky Way and the Magellanic Clouds. However, the binary formati…
GRB 210619B optical afterglow polarization
N. Mandarakas, D. Blinov, D. R. Aguilera-Dena +7
We report on the follow-up of the extremely bright long gamma-ray burst GRB~210619B with optical polarimetry. We conducted optopolarimetric observations of the optical afterglow of…
Jet-Cocoon Geometry in the Optically Dark, Very High Energy Gamma-ray Burst 201216C
L. Rhodes, A. J. van der Horst, R. Fender +4
We present the results of a radio observing campaign on GRB 201216C, combined with publicly available optical and X-ray data. The detection of very high energy (VHE, >100GeV) emiss…
Mergers prompted by dynamics in compact, multiple-star systems: a stellar-reduction case for the massive triple TIC 470710327
Alejandro Vigna-Gómez, Bin Liu, David R. Aguilera-Dena +3
TIC 470710327, a massive compact hierarchical triple-star system, was recently identified by NASA's Transiting Exoplanet Survey Satellite (TESS). TIC 470710327 is comprised of a co…
Stripped-envelope stars in different metallicity environments. II. Type I supernovae and compact remnants
David R. Aguilera-Dena, Bernhard Müller, John Antoniadis +4
Stripped-envelope stars can be observed as Wolf-Rayet (WR) stars, or as less luminous hydrogen-poor stars with low mass loss rates and transparent winds. Both types are potential p…
Thermonuclear and Electron-Capture Supernovae from Stripped-Envelope Stars
Savvas Chanlaridis, John Antoniadis, David R. Aguilera-Dena +3
(abridged) When stripped from their hydrogen-rich envelopes, stars with initial masses between 7 and 11 M develop massive degenerate cores and collapse. Depending on…
Stripped-Envelope Stars in Different Metallicity Environments I. Evolutionary Phases, Classification and Populations
David R. Aguilera-Dena, Norbert Langer, John Antoniadis +5
Massive stars that become stripped of their hydrogen envelope through binary interaction or winds can be observed either as Wolf-Rayet stars, if they have optically thick winds, or…
Explodability fluctuations of massive stellar cores enable asymmetric compact object mergers such as GW190814
John Antoniadis, David R. Aguilera-Dena, Alejandro Vigna-Gómez +6
The first three observing runs with Advanced LIGO and Virgo have resulted in the detection of binary black hole mergers (BBH) with highly unequal mass components, which are difficu…
A three-dimensional hydrodynamics simulation of oxygen-shell burning in the final evolution of a fast-rotating massive star
Takashi Yoshida, Tomoya Takiwaki, David R. Aguilera-Dena +5
We perform for the first time a 3D hydrodynamics simulation of the evolution of the last minutes pre-collapse of the oxygen shell of a fast-rotating massive star. This star has an…
Fallback supernova assembly of heavy binary neutron stars and light black hole-neutron star pairs and the common stellar ancestry of GW190425 and GW200115
Alejandro Vigna-Gómez, Sophie L. Schrøder, Enrico Ramirez-Ruiz +4
The detection of the unusually heavy binary neutron star merger GW190425 marked a stark contrast to the mass distribution from known Galactic pulsars in double neutron star binarie…
Pre-collapse Properties of Superluminous Supernovae and Long Gamma-Ray Burst Progenitor Models
David R. Aguilera-Dena, Norbert Langer, John Antoniadis +1
We analyze the properties of 42 rapidly rotating, low metallicity, quasi-chemically homogeneously evolving stellar models in the mass range between 4 and 45 at…
Supernovae Ib and Ic from the explosion of helium stars
Luc Dessart, Sung-Chul Yoon, David R. Aguilera-Dena +1
Much difficulty has so far prevented the emergence of a consistent scenario for the origin of Type Ib and Ic supernovae (SNe). Here, we follow a heuristic approach by examining the…
The origin of pulsating ultra-luminous X-ray sources: Low- and intermediate-mass X-ray binaries containing neutron star accretors
Devina Misra, Tassos Fragos, Thomas Tauris +2
Ultra-luminous X-ray sources (ULXs) are those X-ray sources located away from the centre of their host galaxy with luminosities exceeding the Eddington limit of a stellar-mass blac…
