A Sub-Saturn Mass Planet, MOA-2009-BLG-319Lb [PDF]
, 2011 We report the gravitational microlensing discovery of a sub-Saturn mass planet, MOA-2009-BLG-319Lb, orbiting a K- or M-dwarf star in the inner Galactic disk or Galactic bulge.

OGLE-2003-BLG-262: Finite-Source Effects from a Point-Mass Lens
, 2003 We analyze OGLE-2003-BLG-262, a relatively short, t_E=12.5+-0.1day, microlensing event generated by a point-mass lens transiting the face of a K giant source in the Galactic bulge.

Climate modelling of mass-extinction events: a review
International Journal of Astrobiology, 2009 AbstractDespite tremendous interest in the topic and decades of research, the origins of the major losses of biodiversity in the history of life on Earth remain elusive. A variety of possible causes for these mass-extinction events have been investigated, including impacts of asteroids or comets, large-scale volcanic eruptions, effects from changes in ...

First M87 Event Horizon Telescope Results. V. Physical Origin of the Asymmetric Ring [PDF]
Astrophysical Journal, 2019 The Event Horizon Telescope (EHT) has mapped the central compact radio source of the elliptical galaxy M87 at 1.3 mm with unprecedented angular resolution. Here we consider the physical implications of the asymmetric ring seen in the 2017 EHT data.

A variety of lepton number violating processes related to Majorana neutrino masses [PDF]
, 2004 A Majorana type of the neutrino mass matrix induces a class of lepton number violating processes. Cross sections of these reactions are given in terms of the neutrino mass matrix element, and a semi-realistic event rate is estimated.
