Formation and Evolution of Disk Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1999
We have developed a semianalitical approach to study galaxy formation and evolution in the cosmological context. Disk galaxies (dark matter halo+luminous disk) are considered to be formed through an extended process of gravitational collapse, whose character is determined by the statistical properties of the density fluctuation field assumed here to be

Genome‐wide identification and biological relevance of broccoli aquaporins

open access: yesThe Plant Genome, Volume 15, Issue 4, December 2022., 2022
Abstract Broccoli (Brassica oleracea var. italica) is an important crop worldwide, and its regular consumption is associated with health benefits due to the presence of various bioactive compounds. An optimal water balance and homeostasis are needed for plant growth; in this sense, aquaporins play a crucial role.

Dynamics of the response of dark matter halo to galaxy evolution in IllustrisTNG [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics
We present the dynamical evolution of the dark matter's relaxation response to galaxies and their connection to the astrophysical properties as simulated in the IllustrisTNG suite of cosmological hydrodynamical simulations.

The Physics of Galaxy Formation and Evolution

open access: yes, 2016
The theoretical studies about galaxy formation and evolution are the subject of this Chapter. They started with the recognition that the Hubble sequence is not a simple morphological description of galaxies, but a possible scheme separating and characterizing the physical processes that bring galaxies to their present form.

Galaxy Formation Theory [PDF]

open access: yes, 2010
We review the current theory of how galaxies form within the cosmological framework provided by the cold dark matter paradigm for structure formation. Beginning with the pre-galactic evolution of baryonic material we describe the analytical and numerical

The evolution of the star-forming sequence in hierarchical galaxy formation models. [PDF]

open access: yes, 2014
It has been argued that the specific star formation rates of star forming galaxies inferred from observational data decline more rapidly below z = 2 than is predicted by hierarchical galaxy formation models. We present a detailed analysis of this problem

Internal Secular Evolution in Disk Galaxies: The Growth of Pseudobulges

open access: yes, 2007
Observational and theoretical evidence that internal, slow ("secular") evolution reshapes galaxy disks is reviewed in Kormendy & Kennicutt (2004, ARAA, 42, 603). This update has three aims.

Optimization of micro grid with distributed energy resources using physics based meta heuristic techniques

open access: yesIET Renewable Power Generation, EarlyView., 2023
Optimization of proposed micro grid system is done using physics based meta heuristic methods. A grid connected micro grid consist of solar PV system, wind turbine (WT), micro gas turbine (MT), fuel cell (FC) and battery energy storage system (BESS).

Addressing persistent challenges in digital image analysis of cancer tissue: resources developed from a hackathon

open access: yesMolecular Oncology, EarlyView.
Large multidimensional digital images of cancer tissue are becoming prolific, but many challenges exist to automatically extract relevant information from them using computational tools. We describe publicly available resources that have been developed jointly by expert and non‐expert computational biologists working together during a virtual hackathon
