DISCOVERY OF TeV GAMMA-RAY EMISSION FROM TYCHO’S SUPERNOVA REMNANT [PDF]
, 2011 We report the discovery of TeV gamma-ray emission from the Type Ia supernova remnant (SNR) G120.1+1.4, known as Tycho's SNR. Observations performed in the period 2008–2010 with the VERITAS ground-based gamma-ray observatory reveal weak emission coming ...

The physics of asymmetric supernovae and supernovae remnants [PDF]
Advances in Applied Physics, 2018 We model the circumstellar medium with four density profiles: hyperbolic type, power law type, exponential type and Gaussian type. We solve analytically or numerically the four first-order differential equations which arise in the framework of the classical thin layer approximation.

Puzzling Pulsars and Supernova Remnants [PDF]
International Astronomical Union Colloquium, 2000 AbstractThe fact that the majority of the youngest radio pulsars are surrounded by expanding supernova remnants is strong evidence that neutron stars are produced in the supernovae of massive stars. In many cases, the pulsar appears significantly offset from the geometric centre of the supernova remnant, indicating that the neutron star has moved away ...

ChemistryOpen, EarlyView.A field‐induced slow magnetic relaxation was observed in an ionic pentacoordinated Cu(II) complex with 4‐amino‐3,5‐di‐2‐pyridyl‐4H‐1,2,4‐triazole and azido ligands. The analysis of the relaxation behaviour supports the origin of the slow magnetic relaxation in intramolecular low‐energy vibration modes participating in the one‐phonon direct and two ...

FERMI LARGE AREA TELESCOPE DETECTION OF THE YOUNG SUPERNOVA REMNANT TYCHO [PDF]
, 2011 After almost three years of data taking in sky-survey mode, the Fermi Large Area Telescope has detected γ-ray emission toward Tycho's supernova remnant (SNR).

Missing Titanium in the Asymmetric Supernova Remnant W 49B
The Astrophysical JournalThe progenitor of the W 49B supernova remnant is still under debate. One of the candidates is a jet-driven core-collapse supernova. In such a highly asymmetric explosion, a strong α -rich freeze-out is expected in local high-entropy regions, which should

On the Mass Distribution of Stellar-Mass Black Holes
Open Astronomy, 2014 The observational stellar-mass black hole mass distribution exhibits a maximum at about 8 M⊙. It can be explained via the details of the massive star evolution, supernova explosions, or consequent black hole evolution.

Small Science, EarlyView.A starch‐based carrier conjugated to cetuximab enables targeted siRNA delivery to epidermal growth factor receptor‐overexpressing tumors. The complexes exhibit dual passive and active tumor targeting, effective cellular uptake, and gene silencing, offering a versatile platform for RNA therapeutics in head and neck cancer.

The imprint of a symbiotic binary progenitor on the properties of Kepler's supernova remnant [PDF]
, 2011 We present a model for the type Ia supernova remnant (SNR) of SN 1604, also known as Kepler’s SNR. We find that its main features can be explained by a progenitor model of a symbiotic binary consisting of a white dwarf and an AGB donor star with an ...
