DOI: 10.1002/asna.20240144
Abstract: JWST has made several surprising discoveries, underscored by the “too early” appearance of well‐formed galaxies and supermassive black holes. It recently also uncovered a compact galaxy (JWST‐ER1g) associated with a complete Einstein ring (JWST‐ER1r) at… read more here.

DOI: 10.1038/s41550-024-02296-7
Abstract: Hyperluminous infrared galaxies (HyLIRGs) are the rarest and most extreme starbursts and found only in the distant Universe (z ≳ 1). They have intrinsic infrared (IR) luminosities LIR ≥ 1013 L⊙ and are commonly found to be major mergers. Recently,… read more here.

DOI: 10.1088/1475-7516/2025/07/041
Abstract: The information about the internal structure of a compact object is classically inaccessible to external observers. In this paper, we investigate how quantum corrections to gravitational fields can reveal the internal structure of compact objects… read more here.

DOI: 10.1088/1674-1137/ad6551
Abstract: We study the Einstein images of a charged Rastall AdS black hole (BH) within the fabric of AdS/CFT correspondence. Considering the holographic setup, we analyze the amplitude of the total response function for various values… read more here.

DOI: 10.1103/physrevd.103.103012
Abstract: The effect of gravitational wave of cosmological wavelength on the gravitational lensing is investigated. When the source, deflector, and observer are aligned in a highly symmetric configuration, an Einstein ring will be observed by the… read more here.
