A research team has measured with greater precision the distance to the #galaxy NGC 3783, which has a very active #blackhole at its center.
Until now the estimates were more uncertain: we now know it lies about 137 Mly away, with a much smaller uncertainty than before.

New paper alert! GSU grad student Madison Markham led a study in which we find a Cepheid-based distance to NGC 3783 of D = 42.03 ± 2.98 Mpc, and it has been accepted for publication in ApJ! 🔭 🧪

Extragalactic astronomers: does anyone know of a good list giving locations of the dozen or so most widely observed deep fields? I know I’ve seen something like this recently but can’t find it. TIA.

Elia and Evans turned the extragalactic ruler on the Milky Way: three methods put our star formation rate at 1.4–1.7 M☉/yr, against 1.65. The follow-up asked if our molecular gas dip is peculiar; several PHANGS galaxies have one, all long-bar spirals. Home is a rare type with company.
