Supernova Cosmology: Legacy and Future [PDF]
, 2011 The discovery of dark energy by the first generation of high-redshift supernova surveys has generated enormous interest beyond cosmology and has dramatic implications for fundamental physics.

A Pre-Gaia Census of Nearby Stellar Groups [PDF]
Proceedings of the International Astronomical Union, 2015 The nearest, youngest groups of stars to the Sun provide important samples of age-dated stars for studying circumstellar disk evolution, imaged exoplanets, and brown dwarfs. I briefly comment on the status of the known stellar groups within 100 pc: β Pic,

Possibility of Secondary i- and s-processes Following r-process in the Collapsar Jet
The Astrophysical Journal LettersThe slow and intermediate neutron-capture processes, s - and i -processes, are believed to occur in asymptotic giant branch stars to provide half of the heavy atomic nuclei with A ≥ 90. We suggest a possibility that certain types of outflows found in the

NEOWISE-R Caught the Luminous SN 2023ixf in Messier 101 [PDF]
The Astrophysical JournalDuring routine survey imaging, the reactivated Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE-R) serendipitously caught the Type II supernova SN 2023ixf in Messier 101 on the rise, starting day 3.6 through day 10.9, and again on the ...

Inference of bipolar neutrino flavor oscillations near a core-collapse supernova based on multiple measurements at Earth [PDF]
Physical Review D, 2022 Neutrinos in compact-object environments, such as core-collapse supernovae, can experience various kinds of collective effects in flavor space, engendered by neutrino-neutrino interactions.

Is the PAMELA anomaly caused by supernova explosions near the Earth? [PDF]
, 2009 We show that the anomaly of the positron fraction observed by the PAMELA experiment can be attributed to recent supernova explosion(s) in a dense gas cloud near the Earth. Protons are accelerated around the supernova remnant.

Numerical studies on the link between radioisotopic signatures on Earth and the formation of the Local Bubble. II. Advanced modelling of interstellar 26Al, 53Mn, 60Fe, and 244Pu influxes as traces of past supernova activity in the solar neighbourhood [PDF]
Astronomy & Astrophysics, 2023 Measurements of long-lived radioisotopes provide a means, completely independent of other observational channels, to draw conclusions about near-Earth supernovae (SNe) and thus the origin of the Local Bubble (LB).

Photons from Neutrinos: The Gamma-Ray Echo of a Supernova Neutrino Burst [PDF]
Astrophysical Journal, 2023 When a star undergoes core collapse, a vast amount of energy is released in a ∼10 s long burst of neutrinos of all species. Inverse beta decay in the star’s hydrogen envelope causes an electromagnetic cascade that ultimately results in a flare of gamma ...

Particle acceleration in winds of star clusters [PDF]
Monthly notices of the Royal Astronomical Society, 2021 The origin of cosmic rays in our Galaxy remains a subject of active debate. While supernova remnant (SNR) shocks are often invoked as the sites of acceleration, it is now widely accepted that the difficulties of such sources in reaching PeV energies ...

The Thousand-Pulsar-Array programme on MeerKAT - X. Scintillation arcs of 107 pulsars [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We present the detection of 107 pulsars with interstellar scintillation arcs at 856–1712 MHz, observed with the MeerKAT Thousand Pulsar Array Programme.
