Carnegie Supernova Project-I and -II: Measurements of using Cepheid, TRGB, and SBF Distance Calibration to Type Ia Supernovae
Syed A. Uddin, Christopher R. Burns, Mark M. Phillips +44
We present an analysis of Type Ia Supernovae (SNe~Ia) from both the Carnegie Supernova Project~I (CSP-I) and II (CSP-II), and extend the Hubble diagram from the optical to the near…
A new measurement of the Hubble constant using Type Ia supernovae calibrated with surface brightness fluctuations
N. Khetan, L. Izzo, M. Branchesi +15
We present a new calibration of the peak absolute magnitude of SNe Type Ia based on the Surface Brightness Fluctuations (SBF) method, aimed at measuring the value of the Hubble con…
Dynamical mass inference of galaxy clusters with neural flows
Doogesh Kodi Ramanah, Radosław Wojtak, Zoe Ansari +2
We present an algorithm for inferring the dynamical mass of galaxy clusters directly from their respective phase-space distributions, i.e. the observed line-of-sight velocities and…
Magnified or multiply imaged? - Search strategies for gravitationally lensed supernovae in wide-field surveys
Radosław Wojtak, Jens Hjorth, Christa Gall
Strongly lensed supernovae can be detected as multiply imaged or highly magnified transients. In order to compare the performances of these two observational strategies, we calcula…
On inferring extinction laws in z~6 quasars as signatures of supernova dust
Jens Hjorth, Paul M. Vreeswijk, Christa Gall +1
Unusual extinction curves of high-redshift QSOs have been taken as evidence that dust is primarily produced by supernovae at high redshift. In particular, the 3000 A Todini-Ferrara…
Production of dust by massive stars at high redshift
C. Gall, J. Hjorth, A. C. Andersen
The large amounts of dust detected in sub-millimeter galaxies and quasars at high redshift pose a challenge to galaxy formation models and theories of cosmic dust formation. At z >…
