Radiative Supernova Remnants and Supernova Feedback [PDF]

open access: yesThe Astrophysical Journal, 2020
Abstract Supernova (SN) explosions are a major feedback mechanism, regulating star formation in galaxies through their momentum input. We review the observations of SNRs in radiative stages in the Milky Way, to validate theoretical results regarding the momentum/energy injection from a single SN explosion.

Searches for Violation of CPT Symmetry and Lorentz Invariance with Astrophysical Neutrinos

open access: yesUniverse, 2022
Neutrinos are a powerful tool for searching physics beyond the standard model of elementary particles. In this review, we present the status of the research on charge-parity-time (CPT) symmetry and Lorentz invariance violations using neutrinos emitted ...

Neutrinos from core-collapse supernovae at KM3NeT [PDF]

open access: yesEPJ Web of Conferences, 2023
The SN1987A supernova was the first extragalactic neutrino de- tection, but no further observations have been made since. Detecting neutrinos from a galactic supernova would provide invaluable information on the supernova mechanism and particle behavior ...

Supernovae and cosmology [PDF]

open access: yesNew Astronomy Reviews, 2001
These lecture notes intend to form a short pedagogical introduction to the use of typical type Ia-Supernovae (hereafter SNIa) as standard candles to determine the energy density of the universe. Problems of principle for taking SNIa as cosmological probes are pointed out, and new attempts at solving them are indicated including the empirical width ...

Indonesian Government Strategies On Obtaining Crude Palm Oil (CPO) Market Access To European Union Countries Over The EU Parliament Resolution On Palm Oil And Deforestation Of Rainforest

open access: yesAndalas Journal of International Studies, 2019
Indonesia is the largest producer of palm oil in the world. With Malaysia, palm oil production could account for about eighty percent of global production. Meanwhile, Europe is the country with the third largest CPO export destination for Indonesia after

R-Process with Magnetized Nuclei at Dynamo-Explosive Supernovae and Neutron Star Mergers

open access: yesUniverse, 2021
Nucleosynthesis at latge magnetic induction levels relevant to core-collapse supernovae and neutron star mergers is considered. For respective magnetic fields of a strength up to ten teratesla, atomic nuclei exhibit a linear magnetic response due to the ...

Smoking supernovae [PDF]

open access: yesInternational Journal of Astrobiology, 2007
AbstractThe question ‘Are supernovae important sources of dust?’ is a contentious one. Observations with the Infrared Astronomical Satellite (IRAS) and the Infrared Space Observatory (ISO) only detected very small amounts of hot dust in supernova remnants.

Progenitors of Long-Duration Gamma-ray Bursts

open access: yesGalaxies, 2021
We review the current scenario of long-duration Gamma-ray burst (LGRB) progenitors, and in addition, present models of massive stars for a mass range of 10–150M⊙ with ΔM=10M⊙ and rotation rate v/vcrit=0 to 0.6 with a velocity resolution Δv/vcrit=0.1.

Supernova Statistics [PDF]

open access: yesInternational Astronomical Union Colloquium, 2005
SummaryThe statistics of SN discoveries is used to reveal selection biases of past and current SN searches and to gain insight on the progenitor scenarios for the different SN types. We also report estimates of the SN rate per unit mass in galaxies of different types and on the first attempts to study the evolution of the supernova rate with redshift.
