Website improvements released | 13 Jul 2018

We're pleased to announce that significant new functionality has been added to the SkyMapper website. Upgrades include:

  • The Marz spectrum viewer (https://github.com/Samreay/Marz) has been incorporated into the website. This version of Marz allows users to load spectra from URLs, as well as local files on disk.
  • We've added a new Object Viewer, which allows users to search for SkyMapper object IDs, as well as view a summary page for each object. Summary pages contain the core information about the object, a selection of images, and information from cross-matched catalogues.
  • Cone search requests made via the website ...

Cross-matching Gaia DR2 and GALAH DR2.1 | 4 Jul 2018

The SkyMapper DR1 catalogue has now been cross-matched against both Gaia DR2 and GALAH DR2.1, with the two tables also being available for TAP queries in the 'ext' schema.

The 1.6 billion Gaia DR2 sources have been cross-matched with SkyMapper DR1, with the results appearing in the gaia_dr2_id1 and gaia_dr2_id2 columns in the dr1.master table, which links the SkyMapper object to the closest and second-closest Gaia DR2 sources, respectively. In addition, the ext.gaia_dr2 table has been augmented with its own gaia_dr2_id1 and gaia_dr2_id2 columns, which are the two closest sources when cross-matching Gaia DR2 against itself.

SkyMapper finds fastest-growing black hole in Universe | 15 May 2018

The Australian National University's SkyMapper telescope has discovered the fastest-growing black hole known to exist in the Universe.

"This black hole is growing so rapidly that it's shining thousands of times more brightly than an entire galaxy, due to all of the gases it sucks in daily that cause lots of friction and heat," said Dr Christian Wolf from the ANU Research School of Astronomy and Astrophysics.

"If we had this monster sitting at the centre of our Milky Way galaxy, it would appear 10 times brighter than a full moon. It would appear as an incredibly bright pin-point ...

SkyMapper creates best map of the southern sky | 23 Apr 2018

This article was originally published by ANU News as "ANU astronomers create best map of the southern sky".

Astronomers at ANU have created the most comprehensive map of the southern sky that can be viewed online by anyone around the world.

The map includes about 70,000 individual images, capturing nearly 300 million stars and galaxies.

Lead researcher Dr Christian Wolf from ANU said the map was created using SkyMapper, a 1.3-metre telescope at the ANU Siding Spring Observatory that is creating a full record of the southern sky for astronomers internationally.

"The map of the southern ...
