Multifrequency radio observations of SNR J0536-6735 (N 59B) with associated pulsar [PDF]

Serbian Astronomical Journal, 2012
We present a study of new Australian Telescope Compact Array (ATCA) observations of supernova remnant, SNR J0536-6735. This remnant appears to follow a shell morphology with a diameter of D=36x29 pc (with 1 pc uncertainty in each direction ...

On the nature of Tycho Brahe’s supernova

Frontiers in Astronomy and Space Sciences, 2023
At the 450 years anniversary of its observation, the supernova named after Tycho Brahe, SN 1572, can be explained in the terms used nowadays to characterize Type Ia supernovae (SNe Ia).

Searching for galactic cosmic ray pevatrons with multi-TeV gamma rays and neutrinos

, 2007
The recent HESS detections of supernova remnant shells in TeV gamma-rays confirm the theoretical predictions that supernova remnants can operate as powerful cosmic ray accelerators.

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

What Produced the Ultraluminous Supernova Remnant in NGC 6946? [PDF]

, 1999
The ultraluminous supernova remnant (SNR) in NGC 6946 is the brightest known SNR in X-rays, ~1000 times brighter than Cas A. To probe the nature of this remnant and its progenitor, we have obtained high-dispersion optical echelle spectra.

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

Chemistry – 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.

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

Chemistry – 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.

MHD Interaction of Pulsar Wind Nebulae with SNRs and the ISM

, 2005
In the late 1960s the discovery of the Crab pulsar in its associated supernova remnant, launched a new field in supernova remnant research: the study of pulsar-driven or plerionic supernova remnants.

The First VLBI Image of the Young, Oxygen-Rich Supernova Remnant in NGC 4449 [PDF]

, 2010
We report on sensitive 1.4-GHz VLBI radio observations of the unusually luminous supernova remnant SNR 4449-1 in the galaxy NGC 4449, which gave us the first well-resolved image of this object. The remnant's radio morphology consists of two approximately

Dual‐Stabilized Single‐Site Fe(II) for Catalytic Conversion of CO2 to Propiolic Acid Under Ambient Condition

EcoEnergy, EarlyView.
We develop a highly cost‐effective heterogeneous catalyst for efficient CO2 conversion to propiolic acid under mild conditions via a nano‐confined approach with porous MIL support. ABSTRACT Efficient conversion of carbon dioxide to organics has been a promising outlet for value‐added carbon dioxide consumption.
