Astronomy and astrophysics

Definition

Astronomy and astrophysics are the study of objects and phenomena that are found beyond our solar system. This combines theoretical simulations and observation with both terrestrial and space-craft-borne instruments of the electromagnetic radiation and high-energy particles emitted by celestial bodies.

    Early results from the COSINE-100 experiment—designed to test a much-debated claim of the detection of a dark-matter signal—show no indications of dark matter, providing evidence against the previous claim.

    Accretion onto the surface of a white dwarf typically generates supersoft X-ray emission and broad emission lines due to nuclear fusion. ASASSN-16oh exhibits no visible broad lines, implying there is no surface fusion, and instead, a belt around the dwarf called a spreading layer is the source of the supersoft X-ray emission.

    H2 roaming is associated with H3+ formation when certain organic molecules are exposed to strong laser fields. Here, the mechanistic details and time-resolved dynamics of H3+ formation from a series of alcohols were obtained and found that the product yield decreases as the carbon chain length increases.

    High-angular-resolution observations of the quasar 3C 273 reveal that it has a relatively small but thick disk, viewed nearly face-on, in which material is orbiting the central supermassive black hole.

    Moving shadows have been seen on the circumbinary disk around V4046 Sgr, cast by eclipses of the central binary system. Using geometrical arguments, the degree of flaring of the disk and the distance to the system have been calculated.
