Density Waves Inside Inner Lindblad Resonance: Nuclear Spirals in Disk Galaxies [PDF]
, 1999 We analyze formation of grand-design two-arm spiral structure in the nuclear regions of disk galaxies. Such morphology has been recently detected in a number of objects using high-resolution near-infrared observations.

The evolution of interacting spiral galaxy NGC 5194 [PDF]
, 2015 NGC 5194 (M51a) is a grand-design spiral galaxy and undergoing interactions with its companion. Here, we focus on investigating main properties of its star formation history (SFH) by constructing a simple evolution model, which assumes that the disc ...

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 ...

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 ...

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 ...

Stellar Spiral Structures in Triaxial Dark Matter Haloes [PDF]
, 2015 We employ very high resolution simulations of isolated Milky Way-like galaxies to study the effect of triaxial dark matter haloes on exponential stellar discs. Non-adiabatic halo shape changes can trigger two-armed grand-design spiral structures which extend all the way to the edge of the disc.

Nuclear Spirals as Signatures of Supermassive Black Holes [PDF]
Astrophys.J. 613 (2004) L105-L108, 2004 Recent high resolution images of spiral galaxies show wide varieties of features including nuclear spirals in the central parts. Some of the galaxies show grand-design nuclear spirals. The morphology of grand-design spirals can be further divided by the openness of the arms: tightly wound ones with winding angle of around 3$\pi$ radian and open spirals

Non‐thermal plasma decontamination of microbes: a state of the art
Biotechnology Progress, EarlyView.Abstract Microbial decontamination is a critical concern in various sectors, from healthcare to food processing. Traditional decontamination methods, while effective to a degree, present limitations in terms of environmental impact, efficiency, and potential harm to the target material. This review investigates the emerging realm of non‐thermal plasma (
