TDCOSMO VI: Distance Measurements in Time-delay Cosmography under the Mass-sheet transformation
Geoff C. -F. Chen, Christopher D. Fassnacht, Sherry H. Suyu +3
Time-delay cosmography with gravitationally lensed quasars plays an important role in anchoring the absolute distance scale and hence measuring the Hubble constant, , indepe…
Photometric Redshift Estimation with a Convolutional Neural Network: NetZ
S. Schuldt, S. H. Suyu, R. Cañameras +4
The redshifts of galaxies are a key attribute that is needed for nearly all extragalactic studies. Since spectroscopic redshifts require additional telescope and human resources, m…
HOLISMOKES -- IV. Efficient mass modeling of strong lenses through deep learning
S. Schuldt, S. H. Suyu, T. Meinhardt +4
Modelling the mass distributions of strong gravitational lenses is often necessary to use them as astrophysical and cosmological probes. With the high number of lens systems ($>10^…
Strongly lensed candidates from the HSC transient survey
Dani C. -Y. Chao, James H. -H. Chan, Sherry H. Suyu +5
We present a lensed quasar search based on the variability of lens systems in the HSC transient survey. Starting from 101,353 variable objects with i-band photometry in the HSC tra…
HOLISMOKES -- III. Achromatic Phase of Strongly Lensed Type Ia Supernovae
S. Huber, S. H. Suyu, U. M. Noebauer +5
To use strongly lensed Type Ia supernovae (LSNe Ia) for cosmology, a time-delay measurement between the multiple supernova (SN) images is necessary. The sharp rise and decline of S…
TDCOSMO II: 6 new time delays in lensed quasars from high-cadence monitoring at the MPIA 2.2m telescope
M. Millon, F. Courbin, V. Bonvin +25
We present six new time-delay measurements obtained from -band monitoring data acquired at the Max Planck Institute for Astrophysics (MPIA) 2.2 m telescope at La Silla observa…
