A cosmological intercept tension in local distance ladders
Haotian Dong, Marek Biesiada, Zhoujian Cao +1
The Hubble tension motivates direct tests of the internal consistency of the local distance ladder. We perform forward and backward consistency checks between Type Ia supernovae in…
Revisiting the Hubble Tension with DESI DR2 Baryon Acoustic Oscillation Observations and Machine Learning Methods
Chenfa Zheng, Shuo Cao, Wuzheng Guo +4
One of the key unresolved questions in modern cosmology is the Hubble tension, which arises from the inconsistency between determinations of the Hubble constant () based on ne…
Predictions on the abundance of primordial black holes: results from the SMILE VLBI milli-lensing sample
Xinyue Jiang, Shuo Cao, Marek Biesiada +4
Primordial black holes (PBHs) formed in the early universe represent a well-motivated dark matter candidate. However, their abundance in the intermediate-to-high mass range (…
Gravitational-Wave Image Multiplicity as a Topological Probe of Dark-Matter Core Collapse
Tonghua Liu, Kai Liao, Marek Biesiada +1
Dark-matter self-interactions can drive subhalos through gravothermal core collapse, but conventional lensing observables vary continuously with uncertain inner profiles. We show t…
Probing Dark Matter Substructure with Wave-Optics Distortions of Strongly Lensed LISA Gravitational Waves
Tonghua Liu, Kai Liao, Marek Biesiada +1
Strong lensing changes the phase of a gravitational-wave signal as well as its amplitude and arrival time. We study whether this phase information can distinguish between three dar…
CORN -- Chronometers of Relic Nature I: The first estimate of the expansion rate of the Universe using compact relic galaxies
Krzysztof Lisiecki, Nicola Principi Cavaterra, Agnieszka Pollo +9
Measuring the expansion rate of the Universe is a central challenge in cosmology. Independent and robust methods are essential to validate existing measurements and assess potentia…
Do we really need alternatives to the CDM parameterization after the DESI DR2?
Youri Carloni, Orlando Luongo, Marek Biesiada
We introduce a density-level pivot construction for the Chevallier-Polarski-Linder (CPL) parameterization by defining the normalized dark energy density …
Probing globular clusters parameters through gravitational wave lensing with stellar-mass black hole binaries
Sreekanth Harikumar, Abbas Askar, Michał Bejger +3
Globular clusters (GCs) can act as gravitational lenses for gravitational waves(GWs) in the wave-optics regime, imprinting frequency-dependent signatures on the observed signal. We…
Extragalactic test of General Relativity with time-delay gravitational lenses
Wuzheng Guo, Shuo Cao, Qiumin Wang +4
Strong gravitational lensing, a key prediction of General Relativity (GR), offers a unique environment for examining alternative modified gravity theories. In this Letter, we emplo…
Mock Catalogs of Strongly Lensed Gravitational Waves via a Halo Model Approach with Space-borne Detectors
Mingqi Sun, Kai Liao, Youkai Li +6
Future space-borne gravitational-wave (GW) detectors, such as LISA and DECIGO, are expected to detect a large number of GW events, a fraction of which may be strongly lensed by int…
Metastability in Emergent Dark Energy: A New Framework Confronting Cosmological Observations
Xiaolei Li, Tonghua Liu, Tian-Nuo Li +3
We propose the Metastable Emergent Dark Energy (MEDE) model, a novel phenomenological extension of the Phenomenological (PEDE) and Generalized (GEDE) Emergent Dark Energy framework…
Testing Weak Equivalence Principle with IceCube Event and Blazar
Tian-Cong Wang, Aleksandra Piorkowska - Kurpas, Marek Biesiada +1
Einstein's Weak Equivalence Principle (WEP), the universality of free fall, is a fundamental component of general relativity and other metric theories of gravity. Its validity can…
Hierarchical cosmological constraints through strong lensing distance ratio
Shuaibo Geng, Shuo Cao, Marek Biesiada +3
Strong gravitational lensing provides an independent and powerful probe of cosmic expansion by directly linking observables to cosmological distances. Upcoming surveys such as LSST…
Mock Catalogs of Strongly Lensed Gravitational Waves via A Halo Model Approach with Ground-based Detectors
Youkai Li, Kai Liao, Mingqi Sun +4
As plans for the construction of third-generation gravitational wave (GW) detectors advance, research into strongly lensed GWs has become increasingly critical. It is anticipated t…
Probing Cosmic Expansion and Early Universe with Einstein Telescope
Angelo Ricciardone, Mairi Sakellariadou, Archisman Ghosh +52
Over the next two decades, gravitational-wave (GW) observations are expected to evolve from a discovery-driven endeavour into a precision tool for astrophysics, cosmology, and fund…
