This morning on the arXiv, the 4 NICER collaboration papers on the massive pulsar PSR J0740+6620! Wolff et al. (data), Miller et al. (Illinois-Maryland team analysis), Riley et al. (X-PSI team mass-radius-geometry analysis), Raaijmakers et al. (X-PSI EOS analysis).
All papers were submitted to ApJ Letters prior to our presentation of the results at the April APS meeting and are at this stage still in review, but incorporate changes requested by referees. We'll update the arXiv if there are further changes before the papers are accepted.

This week my @ERC_Research Starting Grant CSINEUTRONSTAR draws to a close. Over the next few days I'll be tweeting about the research that we've done, what we've learned and (of course) what we're still puzzling over.
Why CSI? The subtitle of the proposal was "The physics and forensics of neutron star explosions"...🔥

Thrilled that we can finally share our first NICER neutron star mass-radius results, for pulsar PSR J0030+0451. It’s been quite the ride getting to this point!!

Before I go any further, here’s the link to papers, which are published together in an ApJ Letters Focus Issue.
