Special Issue Information
Dear Colleagues,
The past decades have seen a major step forward in weak gravitational lensing research, firmly establishing it as one of the most powerful, unbiased probes for mapping dark matter distribution, constraining cosmological models and unraveling the physics of cosmic structure formation. The gravitational shear of background galaxy images imprints unique signatures of the intervening gravitational potential; its precision measurement and robust calibration are the cornerstone of weak lensing science, enabling direct mapping of dark matter halos across cosmic time, rigorous tests of general relativity and precision constraints on dark energy. The advent of next-generation wide-field surveys, including Euclid, LSST, Roman and CSST, has ushered in a new era of precision lensing science, while posing unprecedented challenges for high-fidelity shear measurement, systematic error calibration and statistical interpretation.
This Special Issue aims to host cutting-edge theoretical, numerical and observational contributions across all forefront aspects of weak gravitational lensing, to advance shear measurement methodology, calibration techniques and our understanding of fundamental cosmology and dark matter halo physics.
Potential topics include, but are not limited to:
- Weak gravitational lensing shear measurement and systematic error calibration;
- Cosmic shear statistics and cosmological parameter estimation;
- Galaxy-galaxy lensing and dark matter halo characterization;
- Weak lensing mass reconstruction of galaxy clusters and large-scale structure;
- Mitigation of intrinsic alignment and observational systematics for upcoming surveys, including CSST;
- Multi-probe synergies with CMB lensing, galaxy clustering and other cosmological probes;
- Advanced methodological and machine learning applications in lensing data analysis.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Universe is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
