Photometry and Spectroscopy of SN 2024pxl: A Luminosity Link among Type Iax Supernovae

open access: yesThe Astrophysical Journal
We present extensive ultraviolet to optical photometric and optical to near-infrared (NIR) spectroscopic follow-up observations of the nearby intermediate-luminosity ( M _V = −16.81 ± 0.19 mag) Type Iax supernovae (SNe Iax) 2024pxl in NGC 6384.

New Arabic Records From Cairo on Supernovae 1181 and 1006

open access: yesAstronomische Nachrichten, Volume 346, Issue 9, November 2025.
ABSTRACT The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000–5000 year), the unusual star IRAS00500+6713 with a surrounding nebula (Pa‐30) has an expansion age not inconsistent with a SN Iax explosion in ad 1181 under the assumption that neither acceleration nor ...

NtCML19 Is Recruited by Tobacco to Interact With the Deacetylase Protein RsDN3377 of Rhizoctonia solani AG3‐TB, Inhibiting Fungal Infection

open access: yesMolecular Plant Pathology, Volume 26, Issue 11, November 2025.
The deacetylase RsDN3377 is recognised by the calcium‐binding protein NtCML19, which enhances host resistance against Rhizoctonia solani infection by inducing cell death and reactive oxygen species (ROS) accumulation. ABSTRACT The necrotrophic fungal pathogen Rhizoctonia solani anastomosis group 3 (AG3‐TB) is a major cause of global tobacco crop yield ...

The physics of flames in Type Ia supernovae

open access: yesJournal of Physics: Conference Series, 2005
We extend a low Mach number hydrodynamics method developed for terrestrial combustion, to the study of thermonuclear flames in Type Ia supernovae. We discuss the differences between 2-D and 3-D Rayleigh-Taylor unstable flame simulations, and give detailed diagnostics on the turbulence, showing that the kinetic energy power spectrum obeys Bolgiano ...

Extrapolation of Type Ia Supernova Spectra into the Near-infrared Using Principal Component Analysis

open access: yesThe Astrophysical Journal
We present a method of extrapolating the spectroscopic behavior of Type Ia supernovae (SNe Ia) in the near-infrared (NIR) wavelength regime up to 2.30 μ m using optical spectroscopy.

THE LOCAL HOSTS OF TYPE Ia SUPERNOVAE [PDF]

open access: yesThe Astrophysical Journal, 2009
We use multi-wavelength, matched aperture, integrated photometry from GALEX, SDSS and the RC3 to estimate the physical properties of 166 nearby galaxies hosting 168 well-observed Type Ia supernovae (SNe Ia). Our data corroborate well-known features that have been seen in other SN Ia samples.

Early-time Observations of SN 2023wrk: A Luminous Type Ia Supernova with Significant Unburned Carbon in the Outer Ejecta

open access: yesThe Astrophysical Journal
We present extensive photometric and spectroscopic observations of the nearby Type Ia supernova (SN) 2023wrk at a distance of about 40 Mpc. The earliest detection of this SN can be traced back to a few hours after the explosion. Within the first few days,

A Linear Relation between the Color Stretch s BV and the Rising Color Slope of Type Ia Supernovae

open access: yesThe Astrophysical Journal, 2023
Using data from the Complete Nearby (redshift z _host < 0.02) sample of Type Ia Supernovae (CNIa0.02), we find a linear relation between two parameters derived from the B − V color curves of Type Ia supernovae: the color stretch s _BV and the rising ...
