Fundamental physics studies in time domain and multi-messenger astronomy

open access: yesFrontiers in Astronomy and Space Sciences
The era of ime domain and multi-messenger astronomy is not only leading to the development of a much broader set of detectors and instruments for astrophysical observations, but is also providing the means for astronomy to tie directly to cutting-edge ...

Observational data on Galactic supernova remnants III: The supernova remnants within l = 270°-360° [PDF]

open access: yesSerbian Astronomical Journal, 2004
We have collected all the available data of Galactic supernova remnants given in the literature. The data of Galactic supernova remnants located in the Galactic longitude interval l=270°-360°in all the spectral bands are represented in this work. We have

Ladder‐Like Structural Architecture of Layered Magnetic A2.4 Cr8Te14 (A = Rb, Cs) Compounds by Self‐Flux Synthesis

open access: yesChemistry – A European Journal, EarlyView.
A2.4Cr8Te14$A_{2.4}{\rm Cr}_{8}{\rm Te}_{14}$ (A = Rb, Cs) compounds exhibit a layered, ladder‐like Cr‐Te framework uniting structural motives of hollandite‐like and delafossite‐like phases. Alkali atoms are situated both in the interlayer space and tunnels within the Cr8Te14${\rm Cr}_{8}{\rm Te}_{14}$ framework.

Supernovae, by Chandra and XMM-Newton

open access: yesUniverse
X-ray emission from supernovae can arise from multiple interactions during their evolution. The immediate explosion is sufficiently energetic to generate X-rays; so, too, is the impact of the shock as it runs into circumstellar matter from earlier mass ...

Historical Supernovae and Supernova Remnants [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
The oldest historical supernova (SN), recorded by ancient Chinese in 14th Century B.C. on pieces of tortoise shells or bones, is identified with the aid of modern space γ-ray observations. Hard X-rays with energy up to 20 keV were observed from IC 443 by the X-ray satellite Ginga. We infer from these observations the age of IC 443 is ∼ 1000 — 1400 yrs.

Conversion Between 2‐ and 3‐Dimensional Halogen‐Bonded Networks Formed From a Single N‐Oxide/Iodoalkyne Building Block

open access: yesChemistry – A European Journal, EarlyView.
Open halogen‐bonded networks have been prepared from building blocks that incorporate both iodoalkyne halogen bond donors and a pyridine‐N‐oxide halogen bond acceptor. An initially‐formed 3D network containing dioxane in its channels undergoes an unprecedented transition to a 2D material when crystals are exposed to diethyl ether.

Inferring the core-collapse supernova explosion mechanism with three-dimensional gravitational-wave simulations [PDF]

open access: yes
A detection of a core-collapse supernova signal with an Advanced LIGO and Virgo gravitational-wave detector network will allow us to measure astrophysical parameters of the source.

The physics of supernovae [PDF]

open access: yesInternational Astronomical Union Colloquium, 1986
AbstractPresupernova models of massive stars are presented and their explosion by “delayed neutrino transport” examined. A new form of long duration Type II supernova model is also explored based upon repeated encounter with the electron-positron pair instability in stars heavier than about 60 M⊙. Carbon deflagration in white dwarfs is discussed as the
