Searching for the Ashes of Dead Stars
(2023-08-08)
Hydrogen, helium, and trace amounts of lithium were formed during the Big Bang, but most other elements originally formed deep inside stars by the process of nuclear fusion. They were later scattered across the cosmos, ...
Gravity Tests with Pulsars Using New-Generation Radio Telescopes
(2023-05-23)
Pulsar timing is a powerful tool for studying a wide range of questions in fundamental physics, including the equation of state (EOS) of super-dense matter, tests of general relativity (GR) and alternative theories of ...
The dense interstellar medium and star formation across the nearby galaxies NGC 3627 and NGC 253
(2023-10-11)
The star formation process is an essential aspect of galaxy evolution. Observations of star-forming regions from sub-pc to kpc scales revealed a tight correlation between star formation and the emission of high-critical ...
Pulsar Scintillation and Interstellar Lenses
(2024-01-29)
The radio emission of pulsars is scattered within the interstellar medium due to variations of the electron column density. Pulsars are very compact sources of pulsed radiation and, thus, emit spatially coherent radiation ...
The formation mechanisms of classical emission line stars
(2023-10-10)
Classical emission line stars are known fast rotators hosting a decretion disc in which emission lines are formed. Since their discovery in 1866, the formation mechanism of this class of stars has proved difficult to ...
