Galaxies as stochastic systems: why the next breakthrough in galaxy evolution requires one hundred million spectra
Sandro Tacchella, Vasily Belokurov, Harry T. J. Bevins +4
Each galaxy is observed only once along its life, making galaxy evolution fundamentally an inverse statistical problem: time-dependent physics must be inferred from ensembles of si…
The magnitude of the dark ages 21-cm signal in the context of existing early and late time constraints on CDM
H. T. J. Bevins
The dark ages 21-cm signal is a promising probe of the currently unobserved infant universe between the formation of the Cosmic Microwave Background around and the…
Bayesian Anomaly Detection for Ia Cosmology: Automating SALT3 Data Curation
S. A. K. Leeney, W. J. Handley, H. T. J. Bevins +1
Precision cosmology with Type Ia supernovae (SNe Ia) requires robust quality control of large, heterogeneous datasets. Current data processing often relies on manual, subjective re…
Narrowing the discovery space of the cosmological 21-cm signal using multi-wavelength constraints
Jiten Dhandha, Anastasia Fialkov, Thomas Gessey-Jones +6
The cosmic 21-cm signal is a promising probe of the early Universe, owing to its sensitivity to the thermal state of the neutral intergalactic medium (IGM) and properties of the fi…
Radiometer Calibration using Machine Learning
S. A. K. Leeney, H. T. J. Bevins, E. de Lera Acedo +35
Radiometers are crucial instruments in radio astronomy, forming the primary component of nearly all radio telescopes. They measure the intensity of electromagnetic radiation, conve…
Rapid and Late Cosmic Reionization Driven by Massive Galaxies: a Joint Analysis of Constraints from 21-cm, Lyman Line & CMB Data Sets
Peter H. Sims, Harry T. J. Bevins, Anastasia Fialkov +6
Observations of the Epoch of Reionization (EoR) have the potential to answer long-standing questions of astrophysical interest regarding the nature of the first luminous sources an…
Exploiting synergies between JWST and cosmic 21-cm observations to uncover star formation in the early Universe
Jiten Dhandha, Anastasia Fialkov, Thomas Gessey-Jones +6
In the current era of JWST, we continue to uncover a wealth of information about the Universe deep into the Epoch of Reionization. In this work, we use a suite of simulations with…
On the accuracy of posterior recovery with neural network emulators
H. T. J. Bevins, T. Gessey-Jones, W. J. Handley
Neural network emulators are widely used in astrophysics and cosmology to approximate complex simulations inside Bayesian inference loops. Ad hoc rules of thumb are often used to j…
The mass distribution of the first stars can be determined via the 21-cm signal
T. Gessey-Jones, N. S. Sartorio, H. T. J. Bevins +6
The formation of the first stars and the subsequent population of X-ray binaries represents a fundamental transition in the state of the Universe as it evolves from near homogeneit…
Accounting for Noise and Singularities in Bayesian Calibration Methods for Global 21-cm Cosmology Experiments
Christian J. Kirkham, William J. Handley, Jiacong Zhu +6
Due to the large dynamic ranges involved with separating the cosmological 21-cm signal from the Cosmic Dawn from galactic foregrounds, a well-calibrated instrument is essential to…
