A Comparison Between the Half-Light Radii, Luminosities, and UBV Colors of Globular Clusters in M31 and the Galaxy

, 2010
The Milky Way System and the Andromeda galaxy experienced radically different evolutionary histories. Nevertheless, it is found that these two galaxies ended up with globular cluster systems in which individual clusters have indistinguishable ...

Integrative cross‐tissue analysis unveils complement‐immunoglobulin augmentation and dysbiosis‐related fatty acid metabolic remodeling during mammalian aging

iMeta, EarlyView.
Our study provides a comprehensive multi‐omics profile of aging, integrating proteomic, metabolomic, and metagenomic analyses across diverse tissues and plasma. We identified the synergistic amplification of the circulating complement system and tissue‐wide immunoglobulin accumulation as key molecular drivers of inflammaging.

Implications of the Milky Way Travel Velocity for Dynamical Mass Estimates of the Local Group

The Astrophysical Journal, 2022
The total mass of the Local Group (LG) is a fundamental quantity that enables interpreting the orbits of its constituent galaxies and placing the LG in a cosmological context.

A trio of new Local Group galaxies with extreme properties

, 2008
We report on the discovery of three new dwarf galaxies in the Local Group. These galaxies are found in new CFHT/MegaPrime g,i imaging of the south-western quadrant of M31, extending our extant survey area to include the majority of the southern ...

The Detailed Star Formation History in the Spheroid, Outer Disk, and Tidal Stream of the Andromeda Galaxy [PDF]

, 2006
Using the Advanced Camera for Surveys on the Hubble Space Telescope, we have obtained deep optical images reaching stars well below the oldest main sequence turnoff in the spheroid, tidal stream, and outer disk of the Andromeda Galaxy.

The microbiologist's guide to metaproteomics

iMeta, EarlyView.
Metaproteomics within the multi‐omics framework provides a comprehensive view of microbial systems by identifying proteins, quantifying their levels, detecting posttranslational modifications (PTMs), mapping protein–protein interactions (PPIs), and localizing proteins.

The Panchromatic Hubble Andromeda Treasury. XX. The Disk of M31 is Thick

The Astronomical Journal, 2023
We present a new approach to measuring the thickness of a partially face-on stellar disk, using dust geometry. In a moderately-inclined disk galaxy, the fraction of reddened stars is expected to be 50% everywhere, assuming that dust lies in a thin ...

Asymmetric Drift in the Andromeda Galaxy (M31) as a Function of Stellar Age [PDF]

Astrophysical Journal, 2018
We analyze the kinematics of Andromeda’s disk as a function of stellar age by using photometry from the Panchromatic Hubble Andromeda Treasury survey and spectroscopy from the Spectroscopic and Photometric Landscape of Andromeda’s Stellar Halo survey. We

Das zirkumgalaktische Medium

Physik in unserer Zeit, Volume 56, Issue 1, Page 30-37, January 2025.
Galaxien wie die Milchstraße sind umhüllt von einem gigantischen Kokon aus diffusem Gas. Aktuelle Forschungsergebnisse belegen, dass dieses zirkumgalakische Medium eine entscheidende Rolle für die Entstehung und Entwicklung von Galaxien spielt. Zusammenfassung Als zirkumgalaktisches Medium bezeichnet man die gasförmigen Hüllen von Galaxien, die sich ...

Anthropic Principle’s Predicting Symmetric Distribution Matter Strata, Their Physics Laws, and Verifications

Advances in Astronomy, Volume 2019, Issue 1, 2019., 2019
This paper shows anthropic principle’s predicting symmetric distribution matter strata, their physics laws, and verifications, concretely deduces characteristic time, energy, and temperature expressions at different scales, discovers four interesting invariant quantities, shows homeomorphic theorem of space map, and naturally presents a supersymmetric ...
