X-ray Imaging

9.3K
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Flame Photometry: Overview

1.1K
Flame photometry, also known as flame emission spectrometry, is a technique used for the qualitative and quantitative analysis of elements present in a sample using a flame as the source of excitation energy. The concept of flame photometry was realized in the early 1860s by Kirchhoff and Bunsen, who discovered that specific elements emit characteristic radiation when excited in flames. The first instrument developed for this purpose was used to measure sodium (Na) in plant ash using a Bunsen...

Emission Spectra

73.9K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

Atomic Absorption Spectroscopy: Radiation and Light Sources

885
Atomic absorption spectroscopy (AAS) relies on the Beer-Lambert law, which requires that the radiation source emits a narrow range of wavelengths to match the absorption characteristics of the analyte atom. The primary criteria for choosing an appropriate radiation source in AAS is to provide a precise and intense emission at specific wavelengths that will allow accurate detection of the analyte.
Two common narrow-range 'line' sources used in AAS are hollow-cathode lamps (HCLs) and...

Flame Photometry: Lab01:16

Flame Photometry: Lab

637
In a flame photometer, when a solution like potassium chloride is aspirated into the flame, the solvent evaporates, leaving behind dehydrated salt. This salt dissociates into free gaseous atoms in their ground state. Some of these atoms absorb energy from the flame, leading to their excitation. The excited atoms return to the ground state, emitting photons at characteristic wavelengths. Because only electronic transitions are involved, the resulting emission lines are very narrow. The intensity...

Atomic Emission Spectroscopy: Overview01:20

Atomic Emission Spectroscopy: Overview

3.1K
Atomic emission spectroscopy (AES) is an analytical technique used to determine the elemental composition of a sample by analyzing the light emitted from excited atoms. In AES, atoms in a sample are excited to higher energy levels by thermal energy from high-temperature sources, such as plasma, arcs, or sparks. When these excited atoms return to lower energy states, they emit light at specific wavelengths characteristic of each element. The resulting atomic emission spectrum, which consists of...

Area of Science:

  • Astronomy and Astrophysics
  • High-Energy Astrophysics

Background:

  • Supernovae (SNe) emit X-rays, providing crucial insights into their evolution and physics.
  • Existing X-ray data from young SNe are often fragmented and difficult to access.
  • Type IIn SNe are a specific class of supernovae characterized by narrow or intermediate emission lines.

Purpose of the Study:

  • To create a centralized, searchable database of X-ray data from young supernovae.
  • To facilitate the analysis and comparison of X-ray light curves from different SNe.
  • To provide a platform for the astronomical community to contribute and access supernova data.

Main Methods:

  • Compilation of X-ray fluxes and luminosities from published young supernova observations.
  • Development of a web-based interface for data querying, visualization, and download.
  • Standardization of data to a common 0.3-8 keV energy band for inter-comparison.
  • Implementation of a power-law fitting tool for supernova light curve decay analysis.

Main Results:

  • Successfully established the Supernova X-ray Database (SNaX) with data for Type IIn SNe.
  • Database features include customizable plotting, data submission, and power-law fitting.
  • Data is presented in a common energy band (0.3-8 keV) for direct comparison.
  • A mailing list is established for database updates and community engagement.

Conclusions:

  • SNaX provides a valuable resource for studying the X-ray properties of young supernovae.
  • The database is designed for ease of use, data sharing, and future expansion.
  • Future plans include incorporating X-ray data from all available supernova types.
