Investigations of supernovae and supernova remnants in the era of SKA [PDF]

, 2015
Two main physical mechanisms are used to explain supernova explosions: thermonuclear explosion of a white dwarf(Type Ia) and core collapse of a massive star (Type II and Type Ib/Ic).

SN 2024aecx: A Double-peaked Rapidly Evolving Type IIb Supernova at 11 Mpc

The Astrophysical Journal
We present the results of low-resolution spectroscopic and densely sampled multiband photometric follow-up of supernova (SN) 2024aecx. The SN was discovered in the spiral galaxy NGC 3521 (distance ∼ 11 Mpc) within a day after the explosion.

Inferring Type II-P Supernova Progenitor Masses from Plateau Luminosities

The Astrophysical Journal Letters, 2023
Connecting observations of core-collapse supernova explosions to the properties of their massive star progenitors is a long-sought, and challenging, goal of supernova science. Recently, Barker et al.

Comparing the Host Galaxies of Type Ia, Type II and Type Ibc Supernovae

, 2014
We compare the host galaxies of 902 supernovae, including SNe Ia, SNe II and SNe Ibc, which are selected by cross-matching the Asiago Supernova Catalog with the SDSS Data Release 7.

Light echoes - Type II supernovae

The Astrophysical Journal, 1987
Type II supernovae (SNs) light curves show a remarkable range of shapes. Data have been collected for the 12 Type II SNs that have light curve information for more than four months past maximum. Contrary to previous reports, it is found that (1) the decay rate after 100 days past maximum varies by almost an order of magnitude and (2) the light curve ...

Trigonal Bipyramidal Clusters [Tl5]7−: Synthesis and Characterization of the Zintl Phase K7−xAxTl5 (A = Rb, Cs; 0 < x ≤ 2.35)

Chemistry – A European Journal, Volume 31, Issue 70, December 12, 2025.
Mixed alkali metals, potassium and additional rubidium or cesium, allow for the synthesis of a straightforward, electron‐precise Zintl phase K7−xAxTl5. The new phase is characterized by SCXRD, PXRD, and DFT. Its metastability is proven by DSC measurements.

Surface‐Mounted Metal‐Organic Framework for the Adsorption and Sensing of Monoaromatic Pollutants in Water Using Quartz Crystal Microbalance

Advanced Materials Technologies, Volume 10, Issue 23, December 3, 2025.
A hydrophobic metal‐organic framework (UHMOF‐100) is grown on a quartz crystal microbalance sensor for the first time. The device enables real‐time, selective detection of monoaromatic BTEX pollutants in water, demonstrating a new strategy for creating robust chemical sensors for challenging environmental monitoring applications. Abstract Environmental

Locating Type II-P Supernovae Using the Expanding Photosphere Method. I. Comparing Distances from Different Line Velocities

The Astrophysical Journal, 2023
W present the results of our work testing a version of the Expanding Photosphere Method (EPM) used by Hamuy et al. and Dessart & Hillier to calculate distances to Type II-P supernovae, accounting for the deviations of their luminosities from those of ...

Neutrinos from Choked Jets Accompanied by Type-II Supernovae

, 2018
The origin of the IceCube neutrinos is still an open question. Upper limits from diffuse gamma-ray observations suggest that the neutrino sources are either distant or hidden from gamma-ray observations.

Microvascular Health as a Key Determinant of Organismal Aging

Advanced Science, Volume 12, Issue 47, December 18, 2025.
Abstract Aging is a complex, multifaceted process affecting all organ systems, with vascular aging playing a central role in organismal health decline. Beyond its role in circulation, the vascular system acts as a dynamic interface between tissues, influencing countless physiological functions such as tissue regeneration and repair, immune responses ...
