Can Einstein (rings) surf Gravitational Waves?

open access: yesThe Open Journal of Astrophysics, 2023
How does the appearance of a strongly lensed system change if a gravitational wave is produced by the lens? In this work we address this question by considering a supermassive black hole binary at the center of the lens emitting gravitational waves ...

ALMA IMAGING AND GRAVITATIONAL LENS MODELS OF SOUTH POLE TELESCOPE—SELECTED DUSTY, STAR-FORMING GALAXIES AT HIGH REDSHIFTS [PDF]

open access: yes, 2016
The South Pole Telescope has discovered 100 gravitationally lensed, high-redshift, dusty, star-forming galaxies (DSFGs). We present 0.″5 resolution 870 Atacama Large Millimeter/submillimeter Array imaging of a sample of 47 DSFGs spanning , and construct ...

Quantifying Environmental and Line-of-sight Effects in Models of Strong Gravitational Lens Systems [PDF]

open access: yes, 2016
Matter near a gravitational lens galaxy or projected along the line of sight (LOS) can affect strong lensing observables by more than contemporary measurement errors.

Deep convolutional neural networks as strong gravitational lens detectors [PDF]

open access: yes, 2017
Future large-scale surveys with high resolution imaging will provide us with a few $10^5$ new strong galaxy-scale lenses. These strong lensing systems however will be contained in large data amounts which are beyond the capacity of human experts to ...

Salih Vezir Büyük Vezir’e Karşı: Farklı Tarihsel Anlatılarda ʿAlī b. ʿĪsā ve İbnu’l-Furāt’ın Profillerinin Değişimi

open access: yesAnkara Üniversitesi İlahiyat Fakültesi Dergisi, 2022
Araştırmamız büyük olaylar ve tarihsel figürler arasındaki ilişkiyi konu edinmektedir. Büyük olaylar; tarihte önemli kırılmalara yol açan krizler, çöküşler, zaferler gibi hadiselerdir.

Probing dark matter substructure in the gravitational lens HE 0435-1223 with the WFC3 grism [PDF]

open access: yes, 2017
Strong gravitational lensing provides a powerful test of Cold Dark Matter (CDM) as it enables the detection and mass measurement of low mass haloes even if they do not contain baryons.

Wave-theoretical description of the solar gravitational lens [PDF]

open access: yes, 2017
We discuss the propagation of electromagnetic (EM) waves in the post-Newtonian approximation of the general theory of relativity. We consider diffraction of EM waves in the static gravitational field of a massive monopole.

H0LiCOW - III. Quantifying the effect of mass along the line of sight to the gravitational lens HE 0435-1223 through weighted galaxy counts★ [PDF]

open access: yes, 2016
Based on spectroscopy and multiband wide-field observations of the gravitationally lensed quasar HE 0435-1223, we determine the probability distribution function of the external convergence K-ext for this system.

Fixed Points Features in N-Point Gravitational Lenses

open access: yesEast European Journal of Physics, 2019
A set of fixed points in N-point gravitational lenses is studied in the paper. We use complex form of lens mapping to study fixed points. There are some merits of using a complex form over coordinate. In coordinate form gravitational lens is described by
