AstroSat has
recently been in news due to new findings from its UVIT instrument.
A student makes the following claims
while comparing AstroSat with global astronomy missions. Which of the claims
is/are valid?**
Claim A:
"AstroSat
is unique because no other major observatory, including NASA’s Chandra or ESA’s
XMM-Newton, provides simultaneous coverage across UV, optical, soft and
hard X-ray bands."
Claim B:
"UVIT’s
angular resolution surpasses the UV imaging capability of the Hubble Space
Telescope."
Claim C:
"The
Scanning Sky Monitor of AstroSat performs a role analogous to NASA’s RXTE
All-Sky Monitor, i.e., detecting short-lived X-ray transients."
Claim D:
"AstroSat
is operated by the same ground segment that handled India’s deep-space missions
such as MOM, because both fall under ISTRAC."
