Significance of void shape: Neutrino mass from Voronoi void halos?
Adrian E. Bayer, Jia Liu, Christina D. Kreisch +1
Massive neutrinos suppress the growth of cosmic structure on nonlinear scales, motivating the use of information beyond the power spectrum to tighten constraints on the neutrino ma…
Subtracting the kinetic Sunyaev-Zeldovich effect from the cosmic microwave background with surveys of large-scale structure
Simon Foreman, Selim C. Hotinli, Mathew S. Madhavacheril +2
The kinetic Sunyaev-Zeldovich (kSZ) effect will be an important source of cosmological and astrophysical information in upcoming surveys of the cosmic microwave background (CMB). H…
The Atacama Cosmology Telescope: The Persistence of Neutrino Self-Interaction in Cosmological Measurements
Christina D. Kreisch, Minsu Park, Erminia Calabrese +21
We use data from the Atacama Cosmology Telescope (ACT) DR4 to search for the presence of neutrino self-interaction in the cosmic microwave background. Consistent with prior works,…
The CAMELS project: public data release
Francisco Villaescusa-Navarro, Shy Genel, Daniel Anglés-Alcázar +44
The Cosmology and Astrophysics with MachinE Learning Simulations (CAMELS) project was developed to combine cosmology with astrophysics through thousands of cosmological hydrodynami…
The MASSIVE SURVEY XVI. The Stellar Initial Mass Function in the Center of MASSIVE Early-Type Galaxies
Meng Gu, Jenny Greene, Andrew B. Newman +4
The stellar initial mass function (IMF) is a fundamental property in the measurement of stellar masses and galaxy star formation histories. In this work we focus on the most massiv…
The GIGANTES dataset: precision cosmology from voids in the machine learning era
Christina D. Kreisch, Alice Pisani, Francisco Villaescusa-Navarro +4
We present GIGANTES, the most extensive and realistic void catalog suite ever released -- containing over 1 billion cosmic voids covering a volume larger than the observable Univer…
The void halo mass function: a promising probe of neutrino mass
Gemma Zhang, Zack Li, Jia Liu +4
Cosmic voids, the underdense regions in the universe, are particularly sensitive to diffuse density components such as cosmic neutrinos. This sensitivity is enhanced by the match b…
The Quijote simulations
Francisco Villaescusa-Navarro, ChangHoon Hahn, Elena Massara +26
The Quijote simulations are a set of 44,100 full N-body simulations spanning more than 7,000 cosmological models in the hyperplane.…
The bias of cosmic voids in the presence of massive neutrinos
Nico Schuster, Nico Hamaus, Alice Pisani +4
Cosmic voids offer an extraordinary opportunity to study the effects of massive neutrinos on cosmological scales. Because they are freely streaming, neutrinos can penetrate the int…
CDM or self-interacting neutrinos? - how CMB data can tell the two models apart
Minsu Park, Christina D. Kreisch, Jo Dunkley +2
Of the many proposed extensions to the CDM paradigm, a model in which neutrinos self-interact until close to the epoch of matter-radiation equality has been shown to provide a g…
The Neutrino Puzzle: Anomalies, Interactions, and Cosmological Tensions
Christina D. Kreisch, Francis-Yan Cyr-Racine, Olivier Doré
New physics in the neutrino sector might be necessary to address anomalies between different neutrino oscillation experiments. Intriguingly, it also offers a possible solution to t…
Cosmic voids: a novel probe to shed light on our Universe
Alice Pisani, Elena Massara, David N. Spergel +26
Cosmic voids, the less dense patches of the Universe, are promising laboratories to extract cosmological information. Thanks to their unique low density character, voids are extrem…
Massive Neutrinos Leave Fingerprints on Cosmic Voids
Christina D. Kreisch, Alice Pisani, Carmelita Carbone +5
Do void statistics contain information beyond the tracer 2-point correlation function? Yes! As we vary the sum of the neutrino masses, we find void statistics contain information a…
Electron Energy Distributions in HII Regions and Planetary Nebulae: kappa-Distributions Do Not Apply
B. T. Draine, C. D. Kreisch
Some authors have proposed that electron energy distributions in H II regions and planetary nebulae may be significantly nonthermal, and kappa-distributions have been suggested as…
Cosmological Constraints on Horndeski Gravity in Light of GW170817
C. D. Kreisch, E. Komatsu
The discovery of the electromagnetic counterpart to GW170817 severely constrains the tensor mode propagation speed, eliminating a large model space of Horndeski theory. We use the…
Merger Hydrodynamics of the Luminous Cluster RXJ1347.5-1145
C. D. Kreisch, M. E. Machacek, C. Jones +1
We present an analysis of the complex gas hydrodynamics in the X-ray luminous galaxy cluster RXJ1347.5-1145 caught in the act of merging with a subcluster to its southeast using a…
