Title: An ensemble MCDM strategy for orbit design in Genesis-like missions
Doi: http://dx.doi.org/10.1016/j.asr.2025.11.094
Synopsis: “The main goal of this paper is to introduce a new ensemble-based Multi-Criteria Decision-Making (MCDM) strategy to rank multiple orbit configurations and identify those that maximize the objectives of a satellite mission. The strategy combines five diverse MCDM methods with five objective weighting techniques to determine orbit regions that maximize the performance across a set of selected criteria.”

Title: Milliarcsecond-resolution Radio-imaging Survey of Blazar Candidates at 4 < z < 5.4
Doi: http://dx.doi.org/10.3847/1538-4365/ae1ef0
Synopsis: “The primary objective of this study was to investigate the nature of […] distant active galactic nuclei (AGNs) and to confirm their blazar nature. Utilizing the technique of VLBI, we obtained high-resolution radio images of compact core and core–jet structures.”

Title: A comprehensive search for high-velocity X-ray sources: New compact object binary candidates in the Gaia era
Doi: http://dx.doi.org/10.1093/mnras/stag058
Synopsis: “We perform a comprehensive search for high-velocity X-ray sources with large X-ray/optical flux ratios, identifying candidates for interacting black hole or neutron star binaries potentially accelerated by supernova natal kicks.”

Title: A Square Kilometre Array Pulsar Census
Doi:https://doi.org/10.48550/arxiv.2512.16153
Synopsis: “We describe the considerations and strategies one needs to account for when planning an all-sky blind pulsar survey using the SKA. Based on our understanding of the pulsar population, the performance of the now-under-construction SKA elements, and practical constraints such as evading radio frequency interference, we project pulsar survey yields using two complementary methods for a number of illustrative survey designs, combining SKA1-Low and SKA1-Mid Bands 1 and 2 in a variety of ways.”
