The Hubble Constant from SN Refsdal [PDF]
The Astrophysical Journal Letters, 2018 Abstract Hubble Space Telescope observations from 2015 December 11 detected the expected fifth counter-image of supernova (SN) Refsdal at z = 1.49. In this Letter, we compare the time-delay predictions from numerous models with the measured value derived by Kelly et al. from very early data in the light curve of the SN

Holographic realization of constant roll inflation and dark energy: An unified scenario
Physics Letters B, 2023 In the formalism of generalized holographic dark energy, the infrared cut-off LIR is generalized to the form, LIR=LIR(Lp,L˙p,L¨p,⋯,Lf,L˙f,L¨f,⋯,a,H,H˙,H¨,⋯), where Lp and Lf are the particle horizon and the future horizon, respectively (moreover, a is ...

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract During Galileo's closest (“E12”) flyby of Europa, a brief burst of wave activity was recorded by the plasma wave instrumentation, PWS. This was speculatively interpreted by Jia et al. (2018, https://doi.org/10.1038/s41550‐018‐0450‐z) as a 2,100 cm−3 spike in plasma densities from a water plume encounter. While the plasma instrument, PLS, could

The Hitchhiker’s Guide to the Galaxy Catalog Approach for Dark Siren Gravitational-wave Cosmology
The Astronomical Journal, 2023 We outline the “dark siren” galaxy catalog method for cosmological inference using gravitational wave (GW) standard sirens, clarifying some common misconceptions in the implementation of this method. When a confident transient electromagnetic counterpart

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Jupiter's most intense jet at planetographic latitude 23.7°N experiences vigorous planetary‐scale disturbances. The onset consists of the outbreak of 1–3 bright clouds of convective origin developing turbulent plumes. Observed events between 1970 and 2025 shows a cycle of activity with a period in the range of 3.8–5.1 yrs interrupted between ...

British Educational Research Journal, Volume 52, Issue 1, Page 481-516, February 2026.Abstract Higher education in the United Kingdom has dramatically expanded in recent decades, along with questions about its effectiveness in preparing graduates for the labour market. With rising tuition fees and increasing competition for graduate jobs, many students opt to study ‘professional’ subjects—fields closely tied to specific professions ...

The Global Hubble Constant [PDF]
Australian Journal of Physics, 1990 A review of large-scale investigations of the determination of H is presented. The infrared period-luminosity relation of Cepheids gives distances accurate to -2% to nearby galaxies. Based on the distances of M31, MH, N300 and N2403, a DM of 31 ·30 ±O· 20 has been derived to the nearby Virgo cluster from the TF relation of spirals at four wavebands ...
