THE PHYSICS OF GALAXY FORMATION
The New Cosmology, 2005 The epoch of galaxy formation, occurring between one and six billion years after the Big Bang, was initiated by the collapse of over-dense regions of matter, resulting in extraordinary bursts of star formation, rapid growth of massive nuclear black holes, and the rapid structural evolution of the early universe.

Asking the 5 W's for designing next‐generation bioprocessing
AIChE Journal, EarlyView.Abstract Biotechnology is expanding beyond traditional, centralized fermentation and toward next‐generation bioprocessing paradigms that emphasize flexible deployment outside the laboratory with application‐specific performance. However, many bioprocesses fail to translate beyond proof‐of‐concept into industrially viable systems because early design ...

Journal of Astrophysics & Aerospace Technology, 2017 How Stars are formed? At the center of the galaxy we have what is referred to as a black hole. I would describe it as a proton star with similarity to how a stars mechanics work only in the opposite way. Because of the negative polarity protons flow in and are converted to electron.

Advanced Intelligent Systems, EarlyView.This work presents a magnetic bronchoscopy robot with a novel multi‐segment variable stiffness catheter. This catheter can not only move flexibly in the narrow bronchi but also harden according to the need to provide support. Combined with remote wireless magnetic field drive, it provides a more precise and effective solution for biopsy of deep lung ...

The Physics of Galaxy Accretion
How do galaxies get the gas needed to fuel star formation?' remains a fundamental open question, even for the Milky-Way. I will review recent theoretical developments in galaxy accretion physics, which go beyond the classic separation between 'cold' and 'hot' accretion. I will also discuss the potential implications of different accretion modes for the

The THESEUS Space Mission and the Infrared Telescope Calibration Unit
Astronomische Nachrichten, EarlyView.ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an

Identification of clusters of galaxies and physical properties of clusters and their member galaxies [PDF]
Chinese Science Bulletin, 2019 Clusters of galaxies are the largest gravitationally bound systems in the Universe and are located at the knots of cosmic web. They provide powerful constraints on galaxy evolution, the formation of large scale structure of the Universe and many astrophysical processes.

Astronomische Nachrichten, EarlyView.ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...
