Scientists and other people around the world are paying their
respects to Trevor Weekes, a world-renowned astrophysicist, who
was considered a pioneer and visionary in the field of gamma ray
astronomy.  Weekes was born in Ireland, but he moved to Southern
Arizona in the 1970s, where he helped to develop VERITAS - Very
Energetic Radiation Imaging Telescope Array System - on Mount
Hopkins south of Tucson.  Weekes passed away May 26 at the age
of 74 after a battle with cancer.  A memorial was held in Tucson
on Sunday, and was attended by people from different countries,
including John Kildea, who considered Weekes a mentor and
friend.  Kildea met Weekes in Arizona when Kildea came to
conduct postdoctoral research a few years ago.  Originally from
Ireland, Kildea now lives and works in Canada.  "He welcomed
students from Ireland, from other countries into his home, he
and his wife Ann, and made visiting scientists part of their
family," Kildea said.
