The Hubble flow around the Local Group [PDF]
We use updated data on distances and velocities of galaxies in the proximity of the Local Group (LG) in order to establish properties of the local Hubble flow.

Products of locally cyclic groups [PDF]
AbstractWe consider groups of the form $${G} = {AB}$$ G = AB with two locally cyclic subgroups A and B.

Star Formation Histories with Gaia: The Galaxy and Beyond
ESA’s Gaia mission will provide accurate astrometric, photometric and spectroscopic data for millions of stars in the Galaxy and beyond. We discuss the prospects of using this vast amount of astrophysical information for understanding star formation ...

Cotton leaf segmentation with composite backbone architecture combining convolution and attention
Plant leaf segmentation, especially leaf edge accurate recognition, is the data support for automatically measuring plant phenotypic parameters. However, adjusting the backbone in the current cutting-edge segmentation model for cotton leaf segmentation ...

Testing MOND with Local Group spiral galaxies [PDF]
The rotation curves and the relative mass distributions of the two nearby Local Group spiral galaxies, M31 and M33, show discrepancies with Modified Newtonian dynamic (MOND) predictions.

Locally compact groups and locally minimal group topologies
Minimal groups are Hausdorff topological groups G satisfying the open mapping theorem with respect to continuous isomorphisms, i.e., every continuous iso- morphism G → H, with H a Hausdorff topological group, is a topological isomorphism. A topological group (G,τ) is called locally minimal if there exists a neighbourhood V of the identity such that for

The Luminosity Distribution of Local Group Galaxies [PDF]
From a rediscussion of Local Group membership, and of distances to individual galaxies, we obtain $M_V$ values for 35 probable and possible Local Group members.

The Chemistry of the Local Group [PDF]
Simulations of the chemical enrichment histories of ten Local Group (LG) dwarf galaxies are presented, employing empirically-derived star formation histories (SFHs), a rich network of isotopic and elemental nucleosynthetic yields, and a range of prescriptions for supernova (SN)-driven outflows.
