Contribution of stripped nuclear clusters to globular cluster and ultracompact dwarf galaxy populations [PDF]

, 2014
We use the Millennium II cosmological simulation combined with the semi-analytic galaxy formation model of Guo et al. to predict the contribution of galactic nuclei formed by the tidal stripping of nucleated dwarf galaxies to globular cluster (GC) and ...

The early-type dwarf galaxy population of the Hydra I cluster

, 2008
We analyse the properties of the early-type dwarf galaxy population in the Hydra I cluster. We investigate the galaxy luminosity function (LF), the colour-magnitude relation (CMR), and the magnitude-surface brightness relation down to M_V~-10 mag ...

Lambda-Cold Dark Matter, Stellar Feedback, and the Galactic Halo Abundance Pattern [PDF]

, 2005
(Abridged) The hierarchical formation scenario for the stellar halo requires the accretion and disruption of dwarf galaxies, yet low-metallicity halo stars are enriched in alpha-elements compared to similar, low-metallicity stars in dwarf spheroidal ...

Verification of the Fusarium‐Increasing Properties of the Dominant Dwarfing Gene Ddw1 in triticale (×Triticosecale)

Plant Breeding, Volume 144, Issue 2, Page 151-158, April 2025.
ABSTRACT Dwarfing genes that are considerably reducing plant height are used in many cereals. In triticale, the rye‐derived dominant dwarfing gene Ddw1 was introgressed in commercial varieties. It has already been shown that this gene increases Fusarium head blight (FHB) susceptibility in one segregating population.

A CANDIDATE MASSIVE BLACK HOLE IN THE LOW-METALLICITY DWARF GALAXY PAIR MRK 709 [PDF]

, 2014
The incidence and properties of present-day dwarf galaxies hosting massive black holes (BHs) can provide important constraints on the origin of high-redshift BH seeds.

HI Observations Towards the Sagittarius Dwarf Spheroidal Galaxy [PDF]

, 1999
We have measured the 21-cm line of Galactic HI over more than 50 square degrees in the direction of the Sagittarius dwarf spheroidal galaxy. The data show no evidence of HI associated with the dwarf spheroidal which might be consider analogous to the ...

Single‐Cell Hi‐C Technologies and Computational Data Analysis

Advanced Science, Volume 12, Issue 9, March 6, 2025.
This review provides a detailed examination of scHi‐C technologies, offering quantitative evaluations of 13 protocols. It addresses computational challenges arising from data sparsity and presents systematic insights into data analysis methods, including clustering, TAD calling and 3D reconstruction.

It’s a Breeze: The Circumgalactic Medium of a Dwarf Galaxy Is Easy to Strip

The Astrophysical Journal
The circumgalactic medium (CGM) of star-forming dwarf galaxies plays a key role in regulating the galactic baryonic cycle. We investigate how susceptible the CGM of dwarf satellite galaxies is to ram pressure stripping in Milky Way–like environments.

The Outer Edges of Dwarf Irregular Galaxies: Stars and Gas

, 2002
We have in recent years come to view dwarf galaxy evolution in the broader context of the cosmic evolution of large-scale structure. Dwarf galaxies, as the putative building blocks of hierarchical galaxy formation, and also as the most numerous galaxies ...

Gas depletion in Local Group dwarfs on ~250 kpc scales: Ram pressure stripping assisted by internal heating at early times

, 2011
A recent survey of the Galaxy and M31 reveals that more than 90% of dwarf galaxies within 270 kpc of their host galaxy are deficient in HI gas. At such an extreme radius, the coronal halo gas is an order of magnitude too low to remove HI gas through ram ...
