Detection of a possible superluminous supernova in the Epoch of Reionization

Supergiants and SupernovasSome of the largest and most powerful stars in the universe are supergiants. These massive stars are much larger and brighter than our Sun. When a supergiant reaches the end of its life, it can explode in a massive event called a supernova. This explosion releases enormous amounts of energy and spreads elements across space. Understanding supergiants and supernovas helps scientists learn about the life cycle of stars and the formation of new elements in the...

Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

Star FormationStars are born from vast clouds of gas and dust in space called nebulae. Gravity pulls these particles together, causing them to heat up and form a dense core. Nuclear fusion begins when atomic nuclei merge to form heavier elements, releasing immense energy. This marks the birth of a new star. Studying star formation helps scientists understand the evolution of galaxies and the conditions necessary for stars and planets to form.Science and Engineering Practices (SEP): Analyzing...

In atomic emission spectroscopy (AES), high-temperature atomizers excite a broad range of elements and molecules that generate complex emissions from sources such as oxides, hydroxides, and flame combustion products in the flame or plasma. Several strategies can be employed to minimize spectral interferences caused by overlapping emission lines or bands. These include increasing instrument resolution, choosing alternative emission lines, optimally placing the detector in low-background regions,...

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.

Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...
