A few years after its discovery as a magnetar, SGR J1935+2154 started a new burst-active phase on 2020 April 27, accompanied by a large enhancement of its X-ray persistent emission. Radio single bursts were detected during this activation, strengthening the connection between magnetars and fast radio bursts. We report on the X-ray monitoring of SGR J1935+2154 from ~3 days prior to ~3 weeks after its reactivation, using Swift, NuSTAR, and NICER. We detected X-ray pulsations in the NICER and…

No pulsed radio emission during a bursting phase of a Galactic magnetar.
The results suggest that FRB-SGR burst associations are rare, and it is possible that the physical conditions required to achieve coherent radiation in SGR bursts are difficult to satisfy, and that only under extreme conditions could an FRB be associated with an SGR burst.
NICER View of the 2020 Burst Storm and Persistent Emission of SGR 1935+2154
We report NICER observations of the most intense bursting period yet from the magnetar SGR 1935+2154, focusing on 2020 April 28 from 00:40:58 to 16:21:19 UTC, an interval that ends 0.2 bursts/s.

The Galactic magnetar SGR1935+2154 has been reported to produce the first known example of a bright millisecond duration radio burst (FRB 200428) similar to the cosmological population of fast radio
Bursts before Burst: A Comparative Study on FRB 200428-associated X-ray Burst and other FRB-absent X-ray Bursts from SGR J1935+2154
Accompanied by an X-ray burst, the fast radio burst FRB 200428 was recently confirmed to originate from the Galactic magnetar SGR J1935+2154. Just before FRB 200428 was detected, the
A Demonstration of Extremely Low Latency $\gamma$-ray, X-Ray & UV Follow-Up of a Millisecond Radio Transient
We report results of a novel high-energy follow-up observation of a potential Fast Radio Burst. The radio burst was detected by VLA/realfast and followed-up by the Neil Gehrels Swift Observatory in
Multiwavelength Observations of Fast Radio Bursts
The origin and phenomenology of the Fast Radio Burst (FRB) remains unknown in spite of more than a decade of efforts (see [1–5] for a review). Though several models have been proposed to explain the
Stability of Couette flow for 2D Boussinesq system without thermal diffusivity
In this paper, we prove the stability of Couette flow for 2D Navier-Stokes Boussinesq system without thermal diffusivity for the initial perturbation in Gevrey-$\frac{1}{s}$, ($1/3<s\leq 1$). The

. SGR J1935+2154 was discovered in 2016 and is currently one of the most burst-active Soft Gamma-ray Repeaters (SGR), having emitted several X-ray bursts in recent years. In one of our previous
Deep Upper Limit on the Optical Emission during a Hard X-Ray Burst from the Magnetar SGR J1935+2154
In 2021 September the magnetar SGR J1935+2154 entered a stage of burst/flaring activity in the hard X-ray band. On 2021 September 10, we observed SGR J1935+2154 with the fiber-fed fast optical photon

The soft gamma-ray repeater Swift J1555.2−5402 was discovered by means of a short burst detected with Swift BAT on 2021 June 3. Then, 1.6 hr after the burst, the Neutron star Interior Composition


Evidence for the magnetar nature of 1E 161348-5055 in RCW 103
