Euclid Quick Data Release (Q1): The geometry of dark matter halos from extragalactic streams

Euclid Collaboration, N. Starkman, J. Nibauer +295

Wide-field surveys like Euclid mark a new era of extragalactic stellar stream studies. With a large number of streams, it is now possible to constrain the dark matter halos of gala…

Implications of modern mass-loss rates for massive stars

JD Merritt, Simon Stevenson, Andreas Sander +7

Massive stars lose a significant fraction of their mass through stellar winds at various stages of their lives, including on the main sequence, during the red supergiant phase, and…

A NICER View of PSR J0030+0451: Updated Constraints from Six Years of NICER Observations

Yves Kini, Lucien Mauviard, Tuomo Salmi +13

Pulse-profile modeling of rotation-powered millisecond pulsars targeted by NICER has enabled mass--radius constraints of several neutron star sources, with implications for the den…

Impact of Accretion Assumptions on Pulse Profile Modelling of Superburst Oscillations in 4U 1636-536

Yves Kini, Anna L. Watts, Tuomo Salmi +7

Modelling the coherent pulsations observed during thermonuclear bursts offers a valuable method to probe the poorly understood equation of state of dense and cold matter. Here we a…

Parameter constraints for accreting millisecond pulsars with synthetic NICER data

Bas Dorsman, Tuomo Salmi, Anna L. Watts +10

Pulse profile modelling (PPM) is a technique for inferring mass, radius and hotspot properties of millisecond pulsars. PPM is now regularly used for analysis of rotation-powered mi…

Scaling relations for the uncertainty in neutron star radius inferred from pulse profile modelling: the effect of spin rate

Erik Bootsma, Serena Vinciguerra, Anna L. Watts +2

Pulse profile modelling using X-ray data from NICER permits the inference of mass and radius for rotation-powered millisecond pulsars. This in turn constrains the equation of state…
