Analyzing the cosmic architecture in the vicinity of Grand-design and Flocculent spiral galaxies with Local Geometric Index [PDF]
, 2023 We explore the environment of 351 grand-design and 541 flocculent spiral galaxies recently identified employing convolutional neural networks from the $17^{th}$ data release of Sloan Digital Sky Survey. We introduce a novel estimator called the Local Geometric Index to quantify the morphology of the local environment of these 892 spirals.

A Cloud-Scale View of the Molecular Gas Disk in the Whirlpool Galaxy and Beyond [PDF]
EPJ Web of Conferences, 2022 The nearby galaxy M51 (also known as the Whirlpool galaxy) hosts an iconic grand-design spiral pattern and both IRAM facilities conducted the first cloud-scale (∼50 pc resolution) survey of the molecular gas reservoir across a the disk of a massive star ...

Grand Design vs. Multi-Armed Spiral Galaxies: Dependence on Galaxy Structure [PDF]
We developed an algorithm to use Galaxy Zoo 3D spiral arm masks produced by citizen scientist volunteers to semi-automatically classify spiral galaxies as either multi-armed or grand design spirals. Our final sample consists of 299 multi-armed and 245 grand design galaxies.

Dust Emission in Galaxies at Millimeter Wavelengths: Cooling of star forming regions in NGC6946 [PDF]
EPJ Web of Conferences, 2022 Interstellar dust plays an important role in the formation of molecular gas and the heating and cooling of the interstellar medium. The spatial distribution of the mm-wavelength dust emission from galaxies is largely unexplored. The NIKA2 Guaranteed Time

GRAND DESIGN AND FLOCCULENT SPIRALS IN THESPITZERSURVEY OF STELLAR STRUCTURE IN GALAXIES (S4G) [PDF]
The Astrophysical Journal, 2011 Spiral arm properties of 46 galaxies in the Spitzer Survey of Stellar Structure in Galaxies (S4G) were measured at 3.6mu, where extinction is small and the old stars dominate. The sample includes flocculent, multiple arm, and grand design types with a wide range of Hubble and bar types.

J0107a: A Barred Spiral Dusty Star-forming Galaxy at z = 2.467 [PDF]
Astrophysical Journal Letters, 2023 Dusty star-forming galaxies (DSFGs) are among the most massive and active star-forming galaxies during the cosmic noon. Theoretical studies have proposed various formation mechanisms of DSFGs, including major merger-driven starbursts and secular star ...
