Daniel M. Scolnic

About

Daniel M. Scolnic is an Associate Professor of Physics at Duke University, affiliated with the Trinity College of Arts & Sciences, and also holds a position in the Department of Electrical and Computer Engineering at the Pratt School of Engineering. His research focuses on using observational tools to measure the expansion history of the universe, aiming to answer fundamental questions such as the nature of dark energy. Scolnic's work involves analyzing Type Ia supernovae data, contributing to cosmological constraints and understanding cosmic expansion, isotropy, and structure growth. He has been actively involved in several significant projects, including the Dark Energy Survey supernova program and the Dark Energy Bedrock All-sky Supernova Program. His research has led to improved cosmological measurements and insights into evolving dark energy. Scolnic has also contributed to assessing the Vera Rubin Observatory’s ability to discover asteroid impactors, reflecting his broader interest in astrophysics and planetary defense. His academic background includes a Ph.D. from Johns Hopkins University and a B.S. from the Massachusetts Institute of Technology. He has received multiple grants supporting his research, including funding from NASA, the Department of Energy, and the Packard Foundation.

• A Comprehensive Measurement of the Local Value of the Hubble Constant with 1 km s⁻¹ Mpc⁻¹ Uncertainty from the Hubble Space Telescope and the SH0ES Team

  The Astrophysical Journal Letters · 2022 · 2023 citations

  Abstract We report observations from the Hubble Space Telescope (HST) of Cepheid variables in the host galaxies of 42 Type Ia supernovae (SNe Ia) used to calibrate the Hubble constant ( H 0 ). These include the complete sample of all suitable SNe Ia discovered in the last four decades at redshift z ≤ 0.01, collected and calibrated from ≥1000 HST orbits, more than doubling the sample whose size limits the precision of the direct determination of H 0 . The Cepheids are calibrated geometrically fro…

• Multi-messenger Observations of a Binary Neutron Star Merger

  2017 · 1398 citations

  On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors. The Fermi Gamma-ray Burst Monitor independently detected a gamma-ray burst (GRB 170817A) with a time delay of ~1.7 s with respect to the merger time. From the gravitational-wave signal, the source was initially localized to a sky region of 31 deg² at a luminosity distance of 40₋₈⁺⁸ Mpc a…

• The Pantheon+ Analysis: Cosmological Constraints

  The Astrophysical Journal · 2022 · 1182 citations

  Abstract We present constraints on cosmological parameters from the Pantheon+ analysis of 1701 light curves of 1550 distinct Type Ia supernovae (SNe Ia) ranging in redshift from z = 0.001 to 2.26. This work features an increased sample size from the addition of multiple cross-calibrated photometric systems of SNe covering an increased redshift span, and improved treatments of systematic uncertainties in comparison to the original Pantheon analysis, which together result in a factor of 2 improvem…

• Cosmology intertwined: A review of the particle physics, astrophysics, and cosmology associated with the cosmological tensions and anomalies

  Journal of High Energy Astrophysics · 2022 · 1153 citations

  The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good description of a wide range of astrophysical and cosmological data. However, there are a few big open questions that make the standard model look like an approximation to a more realistic scenario yet to be found. In this paper, we list a few important goals that need to be addressed in the next decade, taking into account the current discordances between the different cosmological probes, such as the disagreement in the v…
