THE LOCAL DWARF GALAXIES:BUILDING BLOCKS OFMASSIVE ONES? I.THE FORNAX DWARF GALAXY

Odessa Astronomical Publications, 2008
A chemical evolution of the Local Group dwarf galaxy Fornax is considered in the framework of the merger scenario. We suppose a galactic stellar halo to be formed as separate fragments which then merge; thus, we can calculate the set of such the ...

A Nearby Isolated Dwarf: Star Formation and Structure of ESO 006–001

The Astrophysical Journal, 2023
Observations with the Hubble Space Telescope unexpectedly revealed that the dwarf galaxy ESO 006–001 is a near neighbor to the Local Group at a distance of 2.70 ± 0.11 Mpc.

The zCOSMOS redshift survey: how group environment alters global downsizing trends [PDF]

, 2009
Context. Groups of galaxies are a common environment, bridging the gap between starforming field galaxies and quiescent cluster galaxies. Within groups secular processes could be at play, contributing to the observed strong decrease of star formation ...

THE PAN-STARRS1 MEDIUM-DEEP SURVEY: THE ROLE OF GALAXY GROUP ENVIRONMENT IN THE STAR FORMATION RATE VERSUS STELLAR MASS RELATION AND QUIESCENT FRACTION OUT TO z ∼ 0.8 [PDF]

, 2013
Using a large optically selected sample of field and group galaxies drawn from the Pan-STARRS1 Medium-Deep Survey (PS1/MDS), we present a detailed analysis of the specific star formation rate (SSFR)—stellar mass (M*) relation, as well as the quiescent ...

Roll‐To‐Roll Production of Smart Dressings for Wound Monitoring

Advanced Healthcare Materials, EarlyView.
This study presents a roll‐to‐roll manufactured smart wound dressing capable of visually monitoring key wound biomarkers, including pH, humidity, and temperature. By integrating colorimetric sensors into flexible dressing substrates, the device offers real‐time, equipment‐free insights for infection detection and wound management, representing a ...

Hickson 62.I. Kinematics of NGC4778 [PDF]

, 2006
Detailed studies of the photometric and kinematical properties of compact groups of galaxies are crucial to understand the physics of galaxy interactions and to shed light on some aspects of galaxy formation and evolution.

Dominant galaxies in 2dF groups [PDF]

Proceedings of the International Astronomical Union, 2004
We investigate whether the spectral-type of a locally dominant (most luminous) galaxy can be used to select sets of galaxies that are physically associated (groups). We assume that passive dominants trace a group-like potential, and SF-dominants a field-like environment.

Synergistic Microcrack Engineering and Auxetic Metamaterials for Enhanced Sensitivity in Stretchable Strain Sensors

Advanced Materials Technologies, EarlyView.
A highly sensitive crack‐based piezoresistive strain sensor is developed using a biaxially pre‐stretched multi‐walled carbon nanotubes/Ecoflex composite and integrated with auxetic metamaterials. Biaxial pre‐stretching improves the sensitivity by 56% compared to the uniaxially pre‐stretched strain sensor.
