Search for blue compact dwarf galaxies during quiescence [PDF]

open access: yes, 2008
Blue compact dwarf (BCD) galaxies are metal-poor systems going through a major starburst that cannot last for long. We have identified galaxies which may be BCDs during quiescence (QBCD), i.e., before the characteristic starburst sets in or when it has ...

Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 351-370, March 2026.
Abstract Returned regolith samples from the asteroid Itokawa provide a unique opportunity to compare shock metamorphic effects in unconsolidated regolith materials with those preserved in lithified meteorites, that is, megaregolith. We analyzed four Itokawa particles (Ueda—RA‐QD02‐0519, Narahara—RA‐QD02‐0573, Domon—RA‐QD02‐0588, Ishiuchi—RX‐MD03‐0212 ...

Molecular hydrogen as dark mass in dwarf galaxies [PDF]

open access: yes, 2004
We report here an example of a series of computer simulations of the formation of disk galaxies, including a standard cold dark matter component, gas, and star formation, which result in objects which closely resemble observed giant galaxies, with a ...

Euclid: Early Release Observations – Dwarf galaxies in the Perseus galaxy cluster [Dataset] [PDF]

open access: yes
F. R. Marleau et al.As part of the Euclid ERO series of papers, we have used Euclid imaging of the Perseus cluster to demonstrate the capabilities of the telescope for dwarf galaxy science. The depth, spatial resolution, and FoV have allowed us to detect

Sensitivity of Chloroplast Movements Along an Elevational Gradient Among Three Alpine Plant Species With Different Life History Strategies

open access: yesPhysiologia Plantarum, Volume 178, Issue 2, March/April 2026.
ABSTRACT Chloroplast movements are an important photoprotective mechanism in land plants. The magnitude of chloroplast responses depends on light conditions. We investigated variation in chloroplast movements and leaf physiological traits in three species: a deciduous dwarf shrub, Vaccinium myrtillus, and two wintergreen herbaceous perennials, Homogyne

Measuring the star formation rate density from CNOC2 [PDF]

open access: yes, 2006
This thesis charts the evolution of the Universal Star Formation Rate Density (SFRD) across the redshift range 0.2 < z < 0.6, using the 2nd Canadian Network for Observational Cosmology Survey (CN0C2).

Dwarf Galaxies in Nearby Groups of Galaxies [PDF]

open access: yes, 2011
We have confirmed 19 new dwarf members in five nearby (z ≤ 0.014) groups of galaxies, measured their photometric characteristics and compared the photometric scaling relations of the late-type dwarf galaxies in the field, group and cluster environments ...

X-Ray Bright Active Galactic Nuclei in Local Dwarf Galaxies: Insights from eROSITA

open access: yesThe Astrophysical Journal
Although supermassive black holes (SMBHs) reside in the heart of virtually every massive galaxy, it remains debated whether dwarf galaxies commonly host SMBHs. Because low-mass galaxies may retain memory of the assembly history of their black holes (BHs),
