The Hamburg meteorite fall: Fireball trajectory, orbit, and dynamics [PDF]
Meteoritics and Planetary Science, 2019 The Hamburg (H4) meteorite fell on 17 January 2018 at 01:08 UT approximately 10 km north of Ann Arbor, Michigan. More than two dozen fragments totaling under 1 kg were recovered, primarily from frozen lake surfaces.

Relationship between fireball's shapes and mechanical materials under grinding
Nihon Kikai Gakkai ronbunshu, 2014 The relationship between the elements included in materials and the fire ball obtained by spark test, that is simple, has been examined by using SEM photographing of the fire ball.

Physical Review DThe tentative identification of approximately ten relativistic antihelium (He¯) cosmic-ray events at AMS-02 would, if confirmed, challenge our understanding of the astrophysical synthesis of heavy antinuclei. We propose a novel scenario for the enhanced production of such antinuclei that is triggered by isolated, catastrophic injections of large ...

Strangeness production in heavy ion collisions at SPS and RHIC within two-source statistical model
, 2002 The experimental data on hadron yields and ratios in central Pb+Pb and Au+Au collisions at SPS and RHIC energies, respectively, are analysed within a two-source statistical model of an ideal hadron gas. These two sources represent the expanding system of

Fireball tomography from bottomonia elliptic flow in relativistic heavy-ion collisions
European Physical Journal C: Particles and Fields, 2021 We calculate the elliptic flow of bottomonia produced in Pb $$\,+\,$$ + Pb collisions at $$\sqrt{s_{\mathrm{NN}}}=5.02$$ s NN = 5.02 TeV. We consider temperature-dependent decay widths for the anisotropic escape of various bottomonium states and observe

On the Spectrum and Polarization of Magnetar Flare Emission
Galaxies, 2018 Bursts and flares are among the distinctive observational manifestations of magnetars, isolated neutron stars endowed with an ultra-strong magnetic field ( B ≈ 10 14 – 10 15 G).

A 450-day light curve of the radio afterglow of GRB 970508: Fireball calorimetry
, 1999 We report on the results of an extensive monitoring campaign of the radio afterglow of GRB 970508, lasting 450 days after the burst. The spectral and temporal radio behavior indicate that the fireball has undergone a transition to sub-relativistic ...

Observation of metre-scale impactors by the Desert Fireball Network [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The Earth is impacted by 35-40 metre-scale objects every year. These meteoroids are the low mass end of impactors that can do damage on the ground. Despite this they are very poorly surveyed and characterised, too infrequent for ground based fireball ...
