Building a legacy: |
the LSST transient sky
Building an unprecedented catalog of Solar System Objects
LSST Science Drivers
Mapping the Milky Way and Local Volume
Probing Dark Energy and Dark Matter
Exploring the Transient Optical Sky
To accomplish this, we need:
1) a large telescope mirror to be sensitive - 8m (6.7m)
2) a large field-of-view for sky-scanning speed - 10 deg2
3) high spatial resolution, high quality images - 0.2''/pixels
4) process images in realtime and offline to produce 10M nightly alerts and catalogs of all 37B objects
>=18000 sq degrees
~800 visits per field
2 visits per night (within ~30 min for asteroids)
+ 5x10sq deg Deep Drilling Fields with ~8000 visits
Objective: to provide a science-ready dataset to transform the 4 key science area
Are We There YET????!!!!

Text
Transietsand variabel stars SC
is a word I am borrowing from Margaret Atwood to describe the fact that the future is us.
However loathsome or loving we are, so will we be.
Whereas utopias are the stuff of dream dystopias are the stuff of nightmares, ustopias are what we create together when we are wide awake
US-TOPIA
