Chandra and XMM-Newton X-ray Study on the Core-collapse Supernova Remnant N63A in an H II Region

Hanxiao Chen, Yang Chen, Lei Sun +1

N63A is one of the brightest supernova remnants (SNRs) in the Large Magellanic Cloud and provides an excellent laboratory for studying SNR evolution in an H II region. We present a…

A pulsar escaping an ancient open cluster via tidal stripping

Lei Zhang, Xiaoting Fu, Di Li +21

Open clusters are the primary birthplaces of stars in the Milky Way disk, yet their neutron star progeny are rarely found within them, presumably due to supernova-induced kicks tha…

Review of Machine Learning Models for Solar Energetic Particle Prediction

Spiridon Kasapis, Pouya Hosseinzadeh, Kathryn Whitman +73

Solar energetic particle (SEP) events have attracted increasing attention due to their significant radiation hazards for aviation, spacecraft electronics, and human missions beyond…

A Complete X-ray View of Supernova Remnant W28 with Einstein Probe: Spatial Distribution of Parameters and Origin of the Thermal-Composite Morphology

Yi-Heng Chi, Ping Zhou, Yang Chen +6

It has been an unsolved question what leads a supernova remnant (SNR) to a thermal composite rather than a typical shell-like morphology, and what causes recombining plasma inside…

Evolution of X-ray Gas in SN 1987A from 2007 to 2021: Ring Fading and Ejecta Brightening Unveiled through Differential Emission Measure Analysis

Lei Sun, Salvatore Orlando, Emanuele Greco +4

As the nearest supernova (SN) observed since Kepler's SN of 1604, SN 1987A provides an unprecedented opportunity to study in detail the early evolution of supernova remnants (SNRs)…

Unusual X-ray Oxygen Line Ratios of SN 1987A Arising From the Absorption of Galactic Hot Interstellar Medium

Lei Sun, Salvatore Orlando, Emanuele Greco +5

Recent high-resolution X-ray spectroscopic studies have revealed unusual oxygen line ratios, such as the high O VII forbidden-to-resonance ratio, in several supernova remnants. Whi…

Optical observations of the Galactic SNR HB9 and H II region G159.2+3.3

Jiang-Tao Li, Li-Yuan Lu, Huiyang Mao +4

Context. We present multi-wavelength observations of the Galactic SNR HB9 and the H II region G159.2+3.3 apparently projected nearby, in order to study their properties and potenti…

A Monte-Carlo Simulation on Resonant Scattering of X-ray Line Emission in Supernova Remnants

Yiping Li, Gao-Yuan Zhang, Yang Chen +2

Resonant scattering (RS) of X-ray line emission in supernova remnants (SNRs) may modify the observed line profiles and fluxes and has potential impact on estimating the physical pr…

Thermal X-ray Emission in the Western Half of the LMC Superbubble 30 Dor C

Yi-Heng Chi, Han-Xiao Chen, Yang Chen +4

While 30 Dor C is a unique superbubble in the Large Magellanic Cloud for its luminous non-thermal X-ray emission, the thermal X-ray emission it emanates has not yet been thoroughly…

Upper Limits of Ti Decay Emission in Four Nearby Thermonuclear Supernova Remnants

Jianbin Weng, Ping Zhou, Hagai B. Perets +2

To identify progenitors and investigate evidence of He burning, we searched for decay radiation of freshly synthesized Ti in four young nearby thermonuclear supernova remnan…

Upper limits on the radio pulses from magnetars and a central compact object with FAST

Wan-Jin Lu, Ping Zhou, Pei Wang +5

Magnetars and central compact objects (CCOs) are subgroups of neutron stars that show a number of properties distinguished from canonical radio pulsars. We performed radio observat…
