Disparities in Neonatal Mortalities in the United States
Children, 2023 Objective: We aimed to look for the mortality of Black and White Neonates and compare the Black and White neonates’ mortalities after stratifying the population by many significant epidemiologic and hospital factors.

Monthly Notices of the Royal Astronomical Society, 2002 Recent work by several groups has established the properties of the dwarf satellites to M31. We reexamine the reported kinematics of this group employing a fresh technique we have developed previously. By calculating the distribution of a chi statistic (which we define in the paper) for the M31 system, we conclude that the total mass (disk plus halo ...

Monthly Notices of the Royal Astronomical Society, 2019 Abstract We have analysed Herschel observations of M31, using the ppmap procedure. The resolution of ppmap images is sufficient ($\sim 31\, {\rm pc}$ on M31) that we can analyse far-IR dust emission on the scale of giant molecular clouds.

The Astrophysical Journal Supplement Series, 2015 The reported positions of 964 suspected nova eruptions in M31 recorded through the end of calendar year 2013 have been compared in order to identify recurrent nova candidates. To pass the initial screen and qualify as a recurrent nova candidate two or more eruptions were required to be coincident within 0.1', although this criterion was relaxed to 0.15'

Evidence for a Massive Andromeda Galaxy Using Satellite Galaxy Proper Motions
The Astrophysical Journal, 2023 We present new mass estimates for Andromeda (M31) using the orbital angular momenta of four satellite galaxies (M33, NGC 185, NGC 147, and IC 10) derived from existing proper motions, distances, and line-of-sight velocities. We infer two masses for M31: $

Symposium - International Astronomical Union, 1983 Close inspection of the channel maps which make up the high resolution M31 HI-data set (Brinks, this volume) resulted in finding numerous shell structures and bubble-like regions. To avoid any bias in the interpretation we shall call holes, in the course of this contribution, all those structures where we find a deficiency of neutral gas.

The Astrophysical Journal, 1997 This Letter gives the results of a determination of the thickness and the optimum inclination (i.e., the angle between the galactic plane and the tangent plane) of M31, which are 1.01 kpc and 775, respectively. The method for determining the thickness of spiral galaxies is proposed by Peng, on the basis of the solution of Poisson's equation for a ...

THE WOLF-RAYET CONTENT OF M31 [PDF]
The Astrophysical Journal, 2012 Wolf-Rayet stars are evolved massive stars, and the relative number of WC-type and WN-type WRs should vary with the metallicity of the host galaxy, providing a sensitive test of stellar evolutionary theory. However, past studies of the WR content of M31 have been biased towards detecting WC stars, as their emission line signatures are much stronger ...
