Severe New Limits on the Host Galaxies of Gamma Ray Bursts [PDF]
, 1998 The nature of Gamma Ray Bursts (GRBs) remains a complete mystery, despite the recent breakthrough discovery of low energy counterparts, although it is now generally believed that at least most GRBs are at cosmological distances.

Hyper-accreting tori of Gamma Ray Bursters [PDF]
AIP Conference Proceedings, 2008 We present numerical simulations of axisymmetric magnetised massive tori around rotating black holes taking into account the energy losses due to emission of neutrinos. A realistic equation of state is used which takes into account the energy losses due to dissociation of nuclei. The heating due to neutrino-antineutrino annihilation is not included. We

New Journal of Physics, 2014 Strong shear flow regions found in astrophysical jets are shown to be important dissipation regions, where the shear flow kinetic energy flow is converted into electric and magnetic field energy via shear instabilities.

Deep search for optical counterparts of gamma-ray bursters [PDF]
International Astronomical Union Colloquium, 1995 AbstractPreliminary results are presented of the first (searching) stage of our observational program of the search and study of weak blue star-like objects in the two small γ-ray burst boxes GB 790418 and GB 790613. The basic search purposes are (1) the selection of star-like objects weaker than 23m inside these boxes, (2) the selection of the bluest ...

New 6-cm observations of a large sample of radio SNRs
, 2007 Almost 50 radio SNR objects were selected from Green's catalogue for continuum and polarization observations. We present preliminary results of this observational campaign at 4.7 GHz carried out with Torun 32-metre radio telescope.Comment: 3 pages, 4 ...

The Astrophysical JournalIn this study, we present the pulse profile of the unique and the second-brightest gamma-ray burst GRB 230307A, and analyze its temporal behavior using a joint GECAM–Fermi Gamma-ray Burst Monitor (GBM) time-resolved spectral analysis.

The Effect of Amino Acids on the Formation of Amorphous Calcium Carbonate Nanoparticles
Advanced Functional Materials, EarlyView.Biomineral formation often proceeds via the assembly of amorphous calcium carbonate (ACC) nanoparticles with narrow size distributions. Using in situ SAXS coupled to a stopped‐flow device, we follow synthetic ACC formation with a 10 ms time resolution and show that amino acids narrow the size distribution at low supersaturation, highlighting their key ...

The role of the host—Neutrophil biology
Periodontology 2000, EarlyView., 2023 Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...
