Pan-STARRS

Post by marasama on 14th January 2010, 6:03 pm

Well, Pan-STARRS discovered it's first Supernova. So it is operational?

With WISE and Pan-STARRS, I can't wait for the word of more close by browns dwarfs. Even closer thatn Proxima Centauri, if they exist.

PS1 started regular observing in March 2009, providing scientific date to the PS1 Scientific Consortium.

During commissioning and early scientific observing the following landmarks were noted:

  • An observing rate of several hundred fields per night in five passbands was achieved.
  • The IPP (Image Processing Pipeline proved capable of processing a whole night’s data (600 images) in 15 hours
  • The MOPS (moving object pipeline) works well: 4000 known asteroids have been detected, plus 7 new ones which have been reported to the minor planet center.
  • Nine new supernovae have been discovered.

During the first few months regular observing, concerns arose about image jitter and local atmospheric seeing effects. Although the telescope is sometimes capable of producing excellent images over the entire field with sub-arcsecond resolution, problems with image quality were detected in an unacceptably large fraction of the images PS1 was producing. It was therefore decided to suspend regular observing in September 2009 in order to address these problems.
The telescope will be back on the air by Thanksgiving 2009: testing of the modified mirror support will occur in December/January. Several thermal imaging experiments will be also performed around the telescope. It is hoped to resume full science operation shortly after this.

Checked Wiki, it says it is operational as of Feb 2010.
Has 1 SN under its belt.

Hope we see more stuff coming soon.

article wrote:"As soon as Pan-STARRS turned on, we felt like we were drinking from a
fire hose!" said Berger. He added that they are finding several hundred
transient objects a month, which would have taken a couple of years with
previous facilities.
Pan-Starrs is now drowning in data.

Confirmation of Pan-STARRS-selected Ultracool Dwarfs

We propose to obtain near-IR imaging (relative photometry) using Gemini/NIRI of ultracool brown dwarfs selected from the Pan-STARRS-1 (PS1) all-sky survey. J-band photometry will allow us to filter truly interesting brown dwarfs from astrophysical false positives. This represents a very efficient use of Band-3 time.

conference devoted to the project
https://habu.pst.qub.ac.uk/groups/panstarrsconference/
in the presentation of data at the end of August

for example for brown dwarfs
https://habu.pst.qub.ac.uk/groups/panstarrsconference/wiki/09d44/attachments/926ee/PS1_2010_GoldmanCM.pdf

Multi-epoch y: 1,400 sq.deg. (600 sq.deg. in z)

Discoveries so far
• 4 T0–T4 dwarfs
• 10 L dwarfs, including
• 2 ‘‘blue’’ L dwarfs (probably old, submetallic)
• augurs well of the future

If Pan-STARRS is a direct imaging campaign, its discoveries will be toward the upper-right... probably farther to the right than the right edge of the graph.

There is also a photometric transit search (line in the figure - "ground-based transit survey")

In addition, I mixed up the link

Using a pseudo color representation of the filters, Figure 1 shows the current sky coverage based on 16,747 full camera observations (60 Orthogonal Transfer CCD images each) transferred to the U.S. Naval Observatory Flagstaff Station (NOFS) so far. More frames have been taken, and this count does not include observations taken prior to the Demo Month.
