Discovery of strongly variable X-ray polarization in the neutron star low-mass X-ray binary transient XTE J1701$-$462

Kavli Affiliate: Roger W. Romani | First 5 Authors: Massimo Cocchi, Andrea Gnarini, Sergio Fabiani, Francesco Ursini, Juri Poutanen | Summary: After about 16 years since its first outburst, the transient neutron star low-mass X-ray binary XTE J1701$-$462 turned on again in September 2022, allowing for the first study of its X-ray polarimetric characteristics by […]

Frequency Modulation of Gravitational Waves by Ultralight Scalar Dark Matter

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, , , , | Summary: The oscillating pressure of the ultralight scalar dark matter (DM) can induce the oscillation of the local gravitational potential. Similar to the time-dependent frequency shift for the pulse signals of pulsars, the oscillation of the local gravitational potential can induce […]

No thick carbon dioxide atmosphere on the rocky exoplanet TRAPPIST-1 c

Kavli Affiliate: Laura Schaefer | First 5 Authors: , , , , | Summary: Seven rocky planets orbit the nearby dwarf star TRAPPIST-1, providing a unique opportunity to search for atmospheres on small planets outside the Solar System (Gillon et al., 2017). Thanks to the recent launch of JWST, possible atmospheric constituents such as carbon […]

Outshining by Recent Star Formation Prevents the Accurate Measurement of High-z Galaxy Stellar Masses

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Desika Narayanan, Sidney Lower, Paul Torrey, Gabriel Brammer, Weiguang Cui | Summary: In this paper, we demonstrate that the inference of galaxy stellar masses via spectral energy distribution (SED) fitting techniques for galaxies formed in the first billion years after the Big Bang carries fundamental uncertainties owing […]
