- NICER Proposal Selection Process for GO Cycle 1 is Complete (01 Mar 2019)
The NICER mission is pleased to announce that the proposal selection process for GO Cycle 1 is complete, and observations will begin March 4, 2019. Documents listing selected proposals and approved targets have been released. Target of Opportunity targets requested by more than one proposal have been prioritized according to feedback received from the review panels. If you feel a target has satisfied the trigger criteria, please contact the NICER science team via the NICER Target of Opportunity/Director's Discretionary Time Request form.
- NICER sees the contraction of the corona in a black hole X-ray transient (14 Jan 2019)
NICER made the cover of Nature with an analysis by Kara et al. of the temporal behavior of the X-ray spectrum of the black hole transient system MAXI J1820+070. Their analysis of the time-resolved NICER spectra of this system showed that the inner edge of the accretion disk is near the accreting black hole and that variations in the X-ray spectral lags indicated that the corona shrank over a time interval of a few weeks.
- NICERDAS Version 5 released (24 Oct 2018)
The NICER data reduction software Version 5 was released on Oct 23 2018 with the release of
HEASoft 6.25 . NICERDAS 5.0 includes updates to most tasks and includes new task, nicertimeconv, to do basic time conversions.
- IGR J17591-2342 second re-brightening observed with NICER (21 Sep 2018)
NICER observations of the second re-brightening of the accreting millisecond pulsar IGR J17591-2342 show it reaching its highest flux yet seen, with strong pulsations remaining after almost 60 days post-outburst.
- NICER Guest Observer Program approved by NASA (07 Sep 2018)
NASA has approved a Guest Observer program for NICER. We expect that the Announcement of Opportunity will be released this fall, with proposals due by the end of the calendar year. More information will be posted on the NICER home page when available.
