Crater clusters on Mars:Shedding light on martian ejecta launch conditions
Cratering Mars Meteorites Impact processes
2015/12/25
We have identified two classes of crater clusters on Mars. One class is “small clusters” (crater diameter D ～ tens m, spread over few hundred m), fitting our earlier calculations for the breakup of we...
Are low luminosity GRBs generated by relativistic jets?
low luminosity generated relativistic jets
2011/9/29
Low luminosity gamma-ray bursts (ll-GRBs) constitute a sub-class of gamma-ray bursts (GRBs) that plays a central role in the GRB-supernova connection. While ll-GRBs differ from typical long GRBs (LGRB...
Excursion Set Halo Mass Function and Bias in a Stochastic Barrier Model of Ellipsoidal Collapse
Excursion Set Function Stochastic Barrier Model Ellipsoidal Collapse
2011/9/29
We use the Excursion Set formalism to compute the properties of the halo mass distribution for a stochastic barrier model which encapsulates the main features of the ellipsoidal collapse of dark matte...
