TNS Newsfeed

Here we will notify about new features, modifications, open issues, and any general news and remarks...

 

We have added a full set of python sample codes, kindly written by Nikola Knezevic, 

which can be used to help develop the required scripts to work with the TNS.

The codes cover all the existing APIs:

AT/Classification bulk reports (examples are provided for both JSON and TSV formats),

file uploads, update of proprietary end date, search and get object details.

The sample codes (PHP+Python) can be downloaded from the help page, under the relevant APIs sections.

 

We are very glad to inform that all the TNS discovery & classification reports (those that are the formal
"discoverers"/"classifiers") are now officially indexed on the NASA ADS system.

The bibcodes of the TNS reports begin with either YYYYTNSTR... or YYYYTNSCR...; TR standing for Transient (discovery)
Report, CR standing for Classification Report. The reports are arranged as daily aggregates per the reporting group and
reporter name/s (author/s).

Querying the ADS by object name (e.g. 2016A) or author/s retrieves any relevant TNS reports, so they can be officially
related to and cited.

On the ADS - for an index of a single object, clicking the "Electronic On-line Article" directs to the
discovery/classification certificate on the TNS. If an aggregate report for multiple objects, clicking the "On-line
Data" directs to the aggregate report on the TNS, which includes links to all objects' pages and certificates. 

A total of ~1800 ADS indexes are now (Jun 2017) in place for all TNS reports since the begining of operation in Jan 2016.

 

The KEGS-C14 catalog was added to the TNS, consisting of ~14500 galaxies (PI: Rest).

If willing to receive email notifications whenever a newly reported transient is found to coincide with a galaxy of this catalog,

please remember to check the KEGS-C14 checkbox at the bottom of the MY ACCOUNT page.

We added a display of the PS1 color stamp on the Object page, next to the SDSS thumbnail.

The PS1 stamp (if within the footprint) should become visible within ~1 hr after the appearance of a new object.

 

Improved cone search (on both the search page and in reporting of a new object) to handle computer truncation/rounding problems.

Corrected update of object discoverymag & discmagfilter when object switches to being public.

 

The TNS now manages LIGO GW events, creating for every newly detected event skymaps showing the known public TNS transients that are found to be within the localization contours.
The data of the new events are accessible only to members of groups that are part of the LV-EM MOU.
See the explanations of LIGO GW Events on our help page.

 
A mechanism for association of TNS transients with sources of external catalogs is now active on the TNS, with KEGS being the first such ext. catalog.
  • Whenever a new object is reported to the TNS, a cone search is performed vs sources of the active external catalogs.
  • Every registered TNS user can set on his "My Account" page if he/she wishes to receive immediate email notifications when a new association is found for any of the listed active catalogs.
  • In the search page, under "Advanced search", it's possible to list all objects associated with the selected catalog.
  • In the object page, there's a note for association of the object with ext. catalog/s - "Separated X arcsec from...".

 

If you're using the Chrome browser, check our Chrome extension for a quick link to the TNS search utilities.
From whichever webpage you're on, quickly query the TNS by an object name or coordinates, unclassified ATs or the known classified SNe, and more...

Comments/suggestions are clearly welcome. Enjoy.
