- **VLBA discovery of a resolved source in the candidate black hole X-ray binary AT2019wey**
- The authors use VLBA radio observation to resolve the compact jet from a optically detected Galactic LMXB AT2019wey. They confirmed this system to be black hole X-ray binary in the hard X-ray spectral state.

- **The sample of eight LLAGNs: X-ray properties**
- The author gave properties of 8 LLAGNs derived from XMM-Newton PN X-ray spectra.

- **Rapid Deceleration of Blast Waves Witnessed in Tycho's Supernova Remnant**
- The author claims a rapid deceleration found in the expansion of Tycho's SNR by using Chandra data, indicating the outward shock wave recently hit dense gas. This result favors the single-degenrate scenario, that Tycho's progenitor consists of a WD + stellar companion.

- **Detection of the hard X-ray non-thermal emission from Kepler's supernova remnant**
- The authors report the first hard X-ray (15-30 keV) detection of non-thermal component in Kepler's SNR using HXD-PIN onboard Suzaku. Combined with radio, soft X-ray and TeV upper limit, the broad-band energy spectrum of Kepler's SNR can be described as a one-zone leptonic model.

- **Detection of X-ray pulsations at the lowest observed luminosity of Be/X-ray binary pulsar EXO 2030+375 with AstroSat**
- They present the timing and spectral studies of EXO 2030+375, a Be/X-ray binary pulsar, using AstroSat observations during its Type I outburst. A ~41.3s pulsations at the lowest luminosity was detected for the first time.

- **VZ Sex: X-ray confirmation of its intermediate polar nature**
- They detect a ~20.3 minutes periodic signal in VZ Sex and interpret it as spin period of the white dwarf by Lomb-Scargle method, using XMM-Newton observation. Combining the timing and spectral analysis results, they further classified VZ Sex as an intermediate polar.

- **A search for hard X-ray bursts occurring simultaneously to fast radio bursts in the repeating FRB 121102**
- The magnetar flare model predicts that FRBs may exibit high energy emission in addition to radio burst emission. The authors searched the Swift/BAT event mode data for repeating FRB 121102 but report no X-ray bursts detectable simultaneously or quasi-simultaneously to the fast radio bursts.

- **Correlating spectral and timing properties in the evolving jet of the micro blazar MAXI J1836-194**
- They explore the disk-jet connection by modelling the multi-wavelength emission of MAXI J1836-194 during its 2011 outburst.
They find that the properties of the X-ray power spectrum are correlated with the jet properties.
