Weak gravitational lensing with CO galaxies [PDF]
, 2018 Optical weak lensing surveys have become a powerful tool for precision cosmology, but remain subject to systematic effects that can severely bias cosmological parameter estimates if not carefully removed. We discuss the possibility of performing complementary weak lensing surveys at radio/microwave frequencies, using detections of CO-emitting galaxies ...

steel research international, EarlyView.The in situ agglomeration behavior of semisolid Al–silicate inclusions in Si‐killed steel is studied using high‐temperature confocal scanning laser microscopy. Particle motion and interparticle forces at the steel/argon interface are quantified and compared with a modified capillary interaction model.

, 2000 We review theory and applications of weak gravitational lensing. After summarising Friedmann-Lemaitre cosmological models, we present the formalism of gravitational lensing and light propagation in arbitrary space-times.

Simulating weak gravitational lensing for cosmology [PDF]
, 2011 This thesis will present a new cosmic shear analysis pipeline SUNGLASS (Simulated UNiverses for Gravitational Lensing Analysis and Shear Surveys). SUNGLASS is a pipeline that rapidly generates simulated universes for weak lensing and cosmic shear ...

Observing the dark universe with weak gravitational lensing
, 2020 We are now entering into an era of huge cosmological data sets, with observations testing the current paradigm to high accuracy. By combining different probes of cosmology, we can access new information about our Universe and investigate the systematic ...

Indefinitely Flat Circular Velocities and the Baryonic Tully–Fisher Relation from Weak Lensing [PDF]
Astrophysical Journal LettersWe use a new deprojection formula to infer the gravitational potential around isolated galaxies from weak gravitational lensing. The results imply circular velocity curves that remain flat for hundreds of kiloparsecs, greatly extending the classic result

Unveiling the “Gray Zone”: Characterizing Young People's Moderate STEM Identities
Journal of Research in Science Teaching, EarlyView.ABSTRACT Understanding how students identify with STEM (Science, Technology, Engineering, Mathematics) is crucial for fostering broader and more equitable participation within these fields. While existing research has focused on students who either strongly identify with STEM or disengage from it, this study explores the moderate STEM identities of ...

Forecasts on the dark energy anisotropic stress for the esa euclid survey [PDF]
The cosmological constant Λ seems to be a not satisfactory explanation of the late-time accelerated expansion of the Universe, for which a number of experimental evidences exist; therefore, it has become necessary in the last years to consider ...

A War of Words: Framing the Austrian Civil War through the Language of the Combatants
History, EarlyView.Abstract The Austrian civil war was a four‐day conflict in 1934 between the largest left‐wing paramilitary, the Schutzbund, and government forces aligned with the largest right‐wing paramilitary group, the Heimwehr. The Schutzbund was quickly and brutally suppressed through the use of overwhelming force, armoured vehicles and even artillery deployment ...

Geodesics, accretion disk, gravitational lensing, time delay, and effects on neutrinos induced by a non-commutative black hole [PDF]
Journal of Cosmology and Astroparticle PhysicsThis paper explores gravitational phenomena associated with a non-commutative black hole. Geodesic equations are derived, and a thin accretion disk is analyzed to model the black hole shadow image, considering an optically thin, radiating, and infalling ...
