7 de ago. de 2019 · Fig. 3: Spectroscopic evolution of the three SLSN classes. The evolution can be divided into three key time windows: up to the luminosity peak (top panel); around 50 days, when the ejecta...
Supernova Spectroscopy Although a supernova’s long-term light curve can be used to deduce its all impor-tant “Type” classification, astronomers like to classify them as soon as the discov-eries are made. The only way to confirm quickly that a suspected supernova really is a supernova (and not an unusual variable star within our own ...
13 de abr. de 2020 · In ‘superluminous’ supernovae of type IIn—named for narrow hydrogen lines 1 in their spectra—the integrated emission can reach 2, 3, 4, 5, 6 ~10 51 erg, attainable by thermalizing most of the...
12 de abr. de 2024 · The discovery of the brightest gamma-ray burst (GRB) to date, GRB 221009A, presented an opportunity to spectroscopically test the idea that r-process elements are produced following the collapse of...
2 de sept. de 2023 · This chapter reviews high-resolution X-ray spectroscopy of SNRs obtained so far. Most results were derived with dispersive spectrometers aboard Einstein, Chandra, and XMM-Newton satellites.
14 de may. de 2024 · We present the largest extragalactic survey of supernova remnant (SNR) candidates in nearby star-forming galaxies using exquisite spectroscopic maps from MUSE. Supernova remnants exhibit distinctive emission-line ratios and kinematic signatures, which are apparent in optical spectroscopy.
This video scans across a plot of brightness measured in flux or intensity of light (y axis) versus wavelength (x axis), moving from blue to red wavelengths from 3800 to 7200 Angstroms. Absorption bands of calcium, silicon, oxygen and iron dominate the spectrum of this Type 1c supernova.
