The circumgalactic medium (CGM), a diffuse gaseous halo surrounding galaxies, plays a critical role in their evolution.

It is still not well understood when and how spiral galaxies first emerged in the early universe and such galaxies are generally rare at high redshifts. To date, only a few individual spirals have ...

Zakamska's team found that the observed gravitational redshifts did indeed match predictions that hotter white dwarfs will be puffier, even if they have the same mass as cooler white dwarfs.
