Search for Short‐Duration Transient Gravitational Waves Emitted by Neutron Star Glitches

Annalen der Physik, Volume 536, Issue 2, February 2024.
The observation rate of pulsar glitches is limited by their electromagnetic observations. There could be a population of the isolated neutron stars in the galaxy for which there is no electromagnetic observations, but they can produce gravitational waves. The all‐sky search for gravitational waves provides better localization of the source sky position

Strontium-84 Enrichments in Presolar Grains Provide First Evidence of p-process Nucleosynthesis in Core-collapse Supernovae

The Astrophysical Journal Letters
This study reports detection of rare p -process isotopes within presolar grains. Presolar grains are relic dust grains from dying stars. These microscopic dust particles are found in primitive solar system materials.

Type Ibc supernovae in disturbed galaxies: evidence for a top-heavy IMF

, 2010
We compare the radial locations of 178 core-collapse supernovae to the R-band and H alpha light distributions of their host galaxies. When the galaxies are split into `disturbed' and `undisturbed' categories, a striking difference emerges.

Chemical Evolution of the Universe and its Consequences for Gravitational‐Wave Astrophysics

Annalen der Physik, Volume 536, Issue 2, February 2024.
Population properties of double compact object mergers (especially binary black holes) are sensitive to the metallicity dependent cosmic star formation history. The uncertainty of this quantity cannot be ignored and makes the interpretation of current gravitational wave observations difficult.

Heavy Elements and Electromagnetic Transients from Neutron Star Mergers

Annalen der Physik, Volume 536, Issue 2, February 2024.
Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...

Discovery of a Relativistic Stripped-envelope Type Ic-BL Supernova at z = 2.83 with JWST

The Astrophysical Journal Letters
We present James Webb Space Telescope (JWST) NIRCam and NIRSpec observations of a Type Ic supernova (SN Ic) and its host galaxy (JADES-GS+53.13533-27.81457) at z = 2.83. This SN (named SN 2023adta) was identified in deep JWST/NIRCam imaging from the JWST

High Redshift Supernova Rates

, 2004
We use a sample of 42 supernovae detected with the Advanced Camera for Surveys on-board the Hubble Space Telescope as part of the Great Observatories Origins Deep Survey to measure the rate of core collapse supernovae to z~0.7 and type Ia supernovae to z~

Shock-cooling Constraints via Early-time Observations of the Type IIb SN 2022hnt

The Astrophysical Journal
We report the results of a rapid follow-up campaign on the Type IIb supernova (SN) 2022hnt. We present a daily, multiband, photometric follow-up using the Las Cumbres Observatory, the Zwicky Transient Facility, the orbiting Swift observatory, and the ...

Exploding Core-Collapse Supernovae with Jittering Jets

, 2011
We argue that jittering jets, i.e., jets that have their launching direction rapidly change, launched by the newly formed neutron star in a core collapse supernova can explode the star.
