A study of the HI and optical properties of Low Surface Brightness galaxies: spirals, dwarfs and irregulars [PDF]
, 2018 We present a study of the HI and optical properties of nearby ($z$ $\le$ 0.1) Low Surface Brightness galaxies (LSBGs). We started with a literature sample of $\sim$900 LSBGs and divided them into three morphological classes: spirals, irregulars and dwarfs.

High Resolution WFPC2 Imaging of IRAS 09104+4109 [PDF]
, 1999 With a infrared luminosity of nearly 10^13 Lsuns, IRAS 09104+4109 is the most luminous galaxy with ...

Chemical evolution of irregular and blue compact galaxies [PDF]
The Astrophysical Journal, 1995 We discuss the chemical evolution of metal poor galaxies and conclude that their oxygen deficiency is not due to: the production of black holes by massive stars or a varying slope of the Initial Mass Function, IMF, at the high-mass end. A varying IMF at the low-mass end alone or in combination with: (a) an outflow of oxygen-rich material, (b) an ...

Journal of Neurochemistry, Volume 169, Issue 1, January 2025.Mars‐bound astronauts will be exposed to unavoidable galactic cosmic radiation (GCR), but the long‐term impact of GCR on females is uncertain. Using touchscreen‐ and arena‐based behavioral tests, we find GCR decreased stimulus–response learning in female mice vs.

Morphological Evolution of Dwarf Galaxies in the Local Group [PDF]
, 2003 The dwarf galaxies of the Local Group can be separated in three morphological groups: irregular, elliptical and spheroidal. As in the large galaxy clusters, there seems to be a morphology-position relationship: irregular galaxies are preferentially found in the outskirts (low density regions) of the Local Group, whereas dwarf ellipticals and ...

The CO contents of dwarf irregular galaxies
The Astrophysical Journal, 1987 A search has been conducted for CO in 16 dwarf irregular galaxies selected to span a wide range of infrared luminosity and color. CO was detected in six dwarf galaxies spanning the entire range in optical color and IR luminosity. The dwarf galaxies extend by three orders of magnitude in luminosity the correlation between IR and CO luminosities found ...

Redshift, metallicity and size of two extended dwarf Irregular galaxies. A link between dwarf Irregulars and Ultra Diffuse Galaxies? [PDF]
, 2017 We present the results of the spectroscopic and photometric follow-up of two field galaxies that were selected as possible stellar counterparts of local high velocity clouds. Our analysis shows that the two systems are distant (D>20 Mpc) dwarf irregular galaxies unrelated to the local HI clouds.

Magnetic Fields in the Irregular Galaxy LMC [PDF]
Symposium - International Astronomical Union, 1993 New radio continuum surveys allowed the determination of the magnetic field in the Large Magellanic Cloud. The magnetic field is filamentary, extending to the south of the 30 Doradus nebula. Some possible explanations for this unusual morphology are discussed.

The effect of vorticity on the feeding of a freshwater grazer
Limnology and Oceanography, Volume 69, Issue S1, Page S54-S66, December 2024.Abstract The transfer of energy through zooplankton grazing on phytoplankton is one of the most important interactions in aquatic ecosystems, yet the role of hydrodynamic forces is not fully understood. Factors that influence these interactions include algal size and shape and the interactions between grazer and alga dictated by hydrodynamic forces ...

On the neutral gas distribution and kinematics in the dwarf irregular galaxy IC 1613 [PDF]
, 2005 Aims. We study the neutral hydrogen distribution and kinematics in the Local Group dwarf irregular galaxy IC 1613 and compare them with the ionized gas distribution and stellar content of the galaxy. We discuss several mechanisms which may be responsible
