A panchromatic spatially resolved analysis of nearby galaxies – II. The main sequence – gas relation at sub-kpc scale in grand-design spirals [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT In this work, we analyse the connection between gas availability and the position of a region with respect to the spatially resolved main-sequence (MS) relation. Following the procedure presented in Enia et al. (2020), for a sample of five face-on, grand design spiral galaxies located on the MS we obtain estimates of stellar ...

Detection of Molecular Clouds in the Interarm of the Flocculent Galaxy NGC 5055

, 2003
We present high-resolution (~ 4") 12CO (J = 1 - 0) mapping observations with high - velocity resolution (~ 2.6 km s^{-1}) toward the disk of flocculent galaxy NGC 5055, using the Nobeyama Millimeter Array in order to study the physical properties of the ...

Stellar Motion around Spiral Arms: Gaia Mock Data [PDF]

, 2014
We compare the stellar motion around a spiral arm created in two different scenarios, transient/co-rotating spiral arms and density-wave-like spiral arms.

Molecules in galaxies. V - CO observations of flocculent and grand-design spirals

The Astrophysical Journal, 1987
New carbon monoxide (1-0) observations of 29 spiral galaxies are presented and combined with previously existing data for 74 galaxies in order to study the dependence of the average CO surface brightness on the spiral-arm class. The total sample shows no significant correlation between the CO surface brightness and the presence or absence of grand ...

Galaxy Zoo: star formation versus spiral arm number [PDF]

, 2017
Spiral arms are common features in low-redshift disc galaxies, and are prominent sites of star formation and dust obscuration. However, spiral structure can take many forms: from galaxies displaying two strong ‘grand design’ arms to those with many ...

A Proof‐of‐Concept Assessment of a Novel Wearable Eyelid Muscle Device: A Pre‐Clinical Animal Cadaver Study for Eyelid Closure Restoration

Advanced Robotics Research, EarlyView.
This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Substituent‐Based Modulation of Self‐Assembly and Immunogenicity of Amphipathic Peptides

Advanced Science, EarlyView.
This study systematically investigates how positional and subtle changes, such as substituents on the phenyl ring attached to short amphipathic peptides, influence their self‐assembly, fibril morphology, and immunogenic responses. ABSTRACT Self‐assembled peptide‐based biomaterials provide versatile platforms for biomedical uses, featuring customizable ...

The Flocculent Structure of the Inner Milky Way Disk

The Astronomical Journal
Observations of H i published in 1957 by Westerhout and Schmidt were presented as showing a global face-on view of the spiral structure in the Milky Way. Since then, many studies have attempted to improve on the early map, perhaps presupposing our Galaxy

How do spiral arm contrasts relate to bars, disc breaks and other fundamental galaxy properties? [PDF]

, 2017
We investigate how the properties of spiral arms relate to other fundamental galaxy properties, including bars and disc breaks. We use previously published measurements of those properties, and our own measurements of arm and bar contrasts for a large ...
