Luminosity function and jet structure of Gamma-Ray Burst [PDF]

open access: yes, 2014
The structure of Gamma Ray Burst (GRB) jets impacts on their prompt and afterglow emission properties. The jet of GRBs could be uniform, with constant energy per unit solid angle within the jet aperture, or it could instead be structured, namely with ...

Reclassification of gamma-ray bursts [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2001
We have applied two different automatic classifier algorithms to the BATSE Current GRB Catalog data and we obtain three different classes of GRBs. Our results confirm the existence of a third, intermediate class of GRBs, with mean duration \sim 25-50 s, as deduced from a cluster analysis and from a neural network algorithm.

GRB Progenitor Classification from Gamma-Ray Burst Prompt and Afterglow Observations

open access: yesThe Astrophysical Journal
Using an established classification technique, we leverage standard observations and analyses to predict the progenitors of gamma-ray bursts (GRBs). This technique, utilizing support vector machine statistics, provides a more nuanced prediction than the ...

An Ultrapotent, Ultraeconomical, Antifreeze Polypeptide

open access: yesAdvanced Materials, EarlyView.
Simple and inexpensive polypeptides composed of random copolymers of alanine and glutamic acid are effective antifreezes for applications in foods and biomedicine. The polypeptides, inspired by natural extremophile proteins, inhibit the growth of large ice crystals and prevent damage to sensitive biologics.
