The Concentration-Mass Relation of Massive, Dynamically Relaxed Galaxy Clusters: Agreement Between Observations and $Λ$CDM Simulations

Kavli Affiliate: R. Glenn Morris | First 5 Authors: Elise Darragh-Ford, Adam B. Mantz, Elena Rasia, Steven W. Allen, R. Glenn Morris | Summary: The relationship linking a galaxy cluster’s total mass with the concentration of its mass profile and its redshift is a fundamental prediction of the Cold Dark Matter (CDM) paradigm of cosmic […]

The Dark Side of Using Dark Sirens to Constrain the Hubble-Lemaître Constant

Kavli Affiliate: Xian Chen | First 5 Authors: Liang-Gui Zhu, Xian Chen, , , | Summary: Dark sirens, i.e., gravitational-wave (GW) sources without electromagnetic counterparts, are new probes of the expansion of the universe. The efficacy of this method relies on correctly localizing the host galaxies. However, recent theoretical studies have shown that astrophysical environments […]

TOI-3235 b: a transiting giant planet around an M4 dwarf star

Kavli Affiliate: Robert F. Goeke | First 5 Authors: Melissa J. Hobson, Andrés Jordán, E. M. Bryant, R. Brahm, D. Bayliss | Summary: We present the discovery of TOI-3235 b, a short-period Jupiter orbiting an M-dwarf with a stellar mass close to the critical mass at which stars transition from partially to fully convective. TOI-3235 […]

Observations of R-Process Stars in the Milky Way and Dwarf Galaxies

Kavli Affiliate: Anna Frebel | First 5 Authors: Anna Frebel, Alexander P. Ji, , , | Summary: This chapter presents an overview of the recent progress on spectroscopic observations of metal-poor stars with r-process element signatures found in the Milky Way’s stellar halo and satellite dwarf galaxies. Major empirical lessons related to the origins of […]

Improving initialization and evolution accuracy of cosmological neutrino simulations

Kavli Affiliate: Salman Habib | First 5 Authors: James M. Sullivan, J. D. Emberson, Salman Habib, Nicholas Frontiere, | Summary: Neutrino mass constraints are a primary focus of current and future large-scale structure (LSS) surveys. Non-linear LSS models rely heavily on cosmological simulations — the impact of massive neutrinos should therefore be included in these […]
