Encounters between M33 and Present-day M31 Satellites Hint at a Previous Group Accretion
This work investigates whether two known Andromeda (M31) satellites, Pisces (LGS 3) and Andromeda XVI (And XVI), have interacted with M33, M31’s most massive satellite.

Probability distribution functions of gas in M31 and M51
We present probability distribution functions (PDFs) of the surface densities of ionized and neutral gas in the nearby spiral galaxies M31 and M51, as well as of dust emission and extinction Av in M31. The PDFs are close to lognormal and those for HI and

The Samples and Binary Fractions of Red Supergiants in M31 and M33 by the HST Observations
The binarity of red supergiants (RSGs) influences their evolution and the fate of supernovae. We investigate the binary fraction of RSGs in the Andromeda galaxy (M31) and Triangulum galaxy (M33) using photometry from the Hubble Space Telescope (HST ...

Ring or No Ring—Revisiting the Multiphase Nuclear Environment in M31
Nuclear rings, prevalent in barred galaxies, are essential to understanding gas transport toward galactic nuclei. However, the peculiar nuclear ring in our neighboring galaxy M31 remains poorly understood.

A systematic literature review of the Pay-What-You-Want pricing under PRISMA protocol
This study aims to systematically examine the Pay-What-You-Want (PWYW) pricing model, which has become increasingly popular among innovative strategies. The PWYW model offers an unconventional approach by giving consumers the power to determine the price

Project AMIGA: The Inner Circumgalactic Medium of Andromeda from Thick Disk to Halo
The inner circumgalactic medium (CGM) of galaxies, where disk and halo processes intersect, remains poorly characterized despite its critical role in regulating galaxy evolution.
