Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT (Brightest ...

We have observed the new emission-line object HM Sge in the region of λ6200 of to λ6700 at 6Å mm⁻¹. The line profiles show a huge disparity in width ranging from 35 km sec⁻¹ for [N ii] to 1700 km ...

Using high-resolution 1665/1667 MHz OH line and continuum spectrum observational data from the European VLBI Network and the ...

Since its discovery in 2022, the GHZ2 galaxy has garnered attention from astronomers due to its unique spectrum featuring ...

Over the past 25 years, single-molecule spectroscopy has developed into a widely used tool in multiple disciplines of science. The diversity of routinely recorded emission spectra does underpin the ...

Two slitless Bragg spectrometers were successfully used on a Sun-pointed Skylark rocket flight (SL 304) on May 5, 1966, to measure the solar X-ray emission below 25 Å. The crystals were of potassium ...

An international team of astronomers has employed NASA's Chandra X-ray observatory to perform the most detailed study of a supergiant star known as Wd1-9, which yielded important insights into the ...
