The First Quenched Galaxies: When and How?
The Astrophysical Journal LettersMany quiescent galaxies discovered in the early Universe by JWST raise fundamental questions on when and how these galaxies became and stayed quenched. Making use of the latest version of the semianalytic model GAEA that provides good agreement with the ...

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.

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 ...

Constraining dark energy using real and mock galaxy surveys [PDF]
, 2009 In this thesis, we study how dark energy may be constrained by measurements of large-scale clustering in future galaxy surveys, and through the imprint of a time-varying large-scale potential on the CMB (the integrated Sachs-Wolfe effect).

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.

Clustering and redshift-space distortions in QSO and galaxy surveys [PDF]
, 2006 In this thesis, we exploit the potential of existing QSO and galaxy surveys for investigating the nature of the large scale structure in the Universe. A detailed analysis of clustering and redshift- space distortions allows us to constrain cosmological ...

Anterior Drawer Maneuver to Access Knee Posteromedial Compartment
Arthroscopy Techniques, EarlyView.Abstract Over the years, diagnostic arthroscopy has been the key to accurately diagnosing lesions in the knee. However, accessing the posterior compartment of the knee remains a challenge for upcoming arthroscopy surgeons. Gillquist was the first surgeon to publish a technique for accessing the posteromedial compartment in 1979, following which several

Causal Discovery in Astrophysics: Unraveling Supermassive Black Hole and Galaxy Coevolution
The Astrophysical JournalCorrelation does not imply causation, but patterns of statistical association between variables can be exploited to infer a causal structure (even with purely observational data) with the burgeoning field of causal discovery.
