Far-infrared images and photometry are presented for 201 Luminous and Ultraluminous Infrared Galaxies (LIRGs), enabling detailed studies of AGN and starburst activity in LIRGs in the local universe.

Modeling suggests the large-asteroid impact flux dropped by 1–2 orders of magnitude during the first 1 Gyr of the Solar System’s existence and remained relatively unchanged over the last 3 Gyr.

Lyα halo sizes at high redshift are observed to scale with various host galaxy properties, suggesting that the physical conditions of the circumgalactic medium change with halo mass and/or star formation rates.

Simulations of the flow inside remnants of binary neutron star mergers show that turbulence can significantly affect the structure and survival time of the merger remnant and its gravitational-wave emissions.

A detailed analysis of the white dwarfs in the local 40 pc suggests ages of 6.8–7.0 Gyr for the thin disk and 8.6–8.8 Gyr for the thick disk. The inner galactic halo is estimated to have an age of 9.1–13.9 Gyr.

A study of 22 central galaxies indicates that galaxies with larger stellar mass are more likely to exhibit slow rotation than those with smaller stellar mass. No dependence on host cluster halo mass is seen, however.
