Eclipsing binaries suitable for distance determination in the Andromeda galaxy [PDF]

, 2006
The Local Group galaxies constitute a fundamental step in the definition of cosmic distance scale. Therefore, obtaining accurate distance determinations to the galaxies in the Local Group, and notably to the Andromeda Galaxy (M 31), is essential for ...

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

iMeta, Volume 4, Issue 3, June 2025.
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.

Andromeda XXVIII: A Dwarf Galaxy More Than 350 kpc from Andromeda [PDF]

, 2011
We report the discovery of a new dwarf galaxy, Andromeda XXVIII, using data from the recently released Sloan Digital Sky Survey Data Release 8. The galaxy is a likely satellite of Andromeda, and, at a separation of 365 +17 – 1 kpc, would be one of the ...

Multicolour photometry of the andromeda galaxy star clusters. [PDF]

, 2021
In this study we present new PHAT survey star cluster photometry catalogue of the Andromeda galaxy. For each cluster we measured: centre coordinates, colour and total apertures, background levels and magnitudes for 6 photometric passbands. Using Naujalis

Resolved SPLASH Chemodynamics in Andromeda’s PHAT Stellar Halo and Disk: On the Nature of the Inner Halo along the Major Axis

The Astronomical Journal, 2023
Stellar kinematics and metallicity are key to exploring formation scenarios for galactic disks and halos. In this work, we characterized the relationship between kinematics and photometric metallicity along the line of sight to M31's disk.

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 ...

ANDROMEDA XXIX: A NEW DWARF SPHEROIDAL GALAXY 200 kpc FROM ANDROMEDA [PDF]

The Astrophysical Journal, 2011
We report the discovery of a new dwarf galaxy, Andromeda XXIX, using data from the recently-released Sloan Digital Sky Survey DR8, and confirmed by Gemini North telescope Multi-Object Spectrograph imaging data. And XXIX appears to be a dwarf spheroidal galaxy, separated on the sky by a little more than 15 degrees from M31, with a distance inferred from
