MAXI/GSC 7-Year High and Low Galactic Latitude Source Catalog (3MAXI) (13 Apr 2021)
This catalog of 221 low galactic latitude X-ray sources and 686
high galactic latitude X-ray sources detected by the MAXI Gas Slit Camera
(GSC) in its first 7 years of operations (combining Hori et al. 2018, ApJS,
207, 36 and Kawamuro et al. 2018, ApJS, 238, 33) is now available in Browse
NICER Finds X-ray Boosts in the Crab Pulsar's Radio Bursts (08 Apr 2021)
A global science collaboration using data from NASA's Neutron star Interior Composition Explorer (NICER) telescope has discovered X-ray surges accompanying radio bursts from the pulsar in the Crab Nebula. The finding shows that these giant radio pulses release far more energy than previously suspected.
NICER follow-up of SRGA J181414.6-225604 (08 Apr 2021)
NICER followup observations of a possible new X-ray transient
discovered by the SRG observatory detected a source showing a peak in soft X-rays and a hard non-thermal tail at higher energies. No evidence for temporal variability was seen.
Viewing tool updated (07 Apr 2021)
The Swift pole constraints have been updated in the Viewing
tool. The revised coefficients extrapolate the trend for the next two

NICER and Swift observations of the new outburst of MAXI J1820+070 (30 Mar 2021)
NICER and Swift observations of the black hole X-ray transient MAXI J1820+070 near the start of its outburst found an X-ray luminosity of only 1e33 ergs/s. This is one of the lowest luminosities at which the start of a black hole-X-ray transient outburst has been caught in X-rays.
