Semi-supervised morphological classification of fast radio bursts from the second CHIME/FRB catalogue
Bo Lin Fan, Renée Hložek, Antonio Herrera Martin
The paper introduces a convolutional autoencoder–based unsupervised classifier to group fast radio bursts from the CHIME/FRB catalogue into morphological classes and to predict rep…
Here, There and Everywhere: How AGN jets affect galaxy cluster environments
Isaac Rosenberg, Martine Lokken, Renée Hložek +3
The paper uses zoom‑in hydrodynamic simulations of galaxy clusters to test how AGN jet properties (velocity, orientation, coupling) affect the thermal state of surrounding gas and…
The Atacama Cosmology Telescope: Probing new signatures of ultralight axions with gravitational lensing
Alex Laguë, Keir K. Rogers, Mathew S. Madhavacheril +14
Ultralight axions (ULAs) are well-motivated dark matter particle candidates that arise in many extensions of the Standard Model of particle physics. ULAs with mass $m_\mathrm{a} \l…
Probing Physics Beyond the Standard Model through Combined Analyses of Next-Generation Type Ia Supernova, CMB, and BAO Surveys
Srinivasan Raghunathan, Ayan Mitra, Nikolina Å arÄeviÄ +11
Observations of Type Ia supernovae (\sne), which probe the late Universe, together with baryon acoustic oscillations (BAO) and the cosmic microwave background (CMB), which probe th…
Cosmic voids as a probe of the nature of dark matter: simulations and galaxy survey forecasts
Alexander Spencer London, Keir K. Rogers, Alex Laguë +2
Voids are parts of the cosmic web least affected by non-linearities and baryonic feedback. We thus calculate the sensitivity of voids to the nature of dark matter (DM), using ultra…
Running the small-correlated-against-large estimator at scale: Applications of small-scale CMB lensing estimators on realistic simulations
Victor C. Chan, Renée Hložek, Joel Meyers +1
The Small-Correlated-Against-Large Estimator (SCALE) for small-scale lensing of the cosmic microwave background (CMB) provides a novel method for measuring the amplitude of CMB len…
