Planck 2018 results VII. Isotropy and statistics of the CMB
(EDP Sciences, 2020)
Analysis of the Planck 2018 data set indicates that the statistical properties of the cosmic microwave background (CMB) temperature anisotropies are in excellent agreement with previous studies using the 2013 and 2015 data ...
Improved upper limits on the 21 cm signal power spectrum of neutral hydrogen at z ≈ 9.1 from LOFAR
(Oxford University Press, 2020)
A new upper limit on the 21 cm signal power spectrum at a redshift of z ≈ 9.1 is presented, based on 141 h of data obtained with the Low-Frequency Array (LOFAR). The analysis includes significant improvements in spectrally ...
Planck intermediate results. LVII. Joint Planck LFI and HFI data processing
(ESO, 2020)
We present the NPIPE processing pipeline, which produces calibrated frequency maps in temperature and polarization from data from the Planck
Low Frequency Instrument (LFI) and High Frequency Instrument (HFI) using ...
A flexible method for estimating luminosity functions via Kernel Density Estimation
(IOP Publishing, 2020)
We propose a flexible method for estimating luminosity functions (LFs) based on kernel density
estimation (KDE), the most popular nonparametric density estimation approach developed in modern
statistics, to overcome ...
Significance levels of common frequencies extracted from multiple data sets
(Oxford University Press, 2020)
Large monitoring campaigns, particularly those using multiple filters, have produced replicated time series of observations for literally millions of stars. The search for periodicities in such replicated data can be ...
Unsupervised machine learning for transient discovery in deeper, wider, faster light curves
(Oxford University Press, 2020)
Identification of anomalous light curves within time-domain surveys is often challenging. In addition, with the growing number of wide-field surveys and the volume of data produced exceeding astronomers’ ability for manual ...
Variability and transient search in the SUDARE–VOICE field: A new method to extract the light curves
(Oxford University Press, 2020)
The VLT Survey Telescope (VST) Optical Imaging of the CDFS and ES1 Fields Survey, in
synergy with the SUDARE survey, is a deep optical ugri imaging of the CDFS and ES1 fields
using the VST. The observations for the CDFS ...
All-sky angular power spectrum – I. Estimating brightness temperature fluctuations using the 150-MHz TGSS survey
(Oxford University Press, 2020)
Measurements of the Galactic synchrotron emission are important for the 21-cm studies of the epoch of reionization. The study of synchrotron emission is also useful for quantifying the fluctuations in the magnetic field ...
Planck 2018 results: V. CMB power spectra and likelihoods
(EDP Sciences, 2020)
We describe the legacy Planck cosmic microwave background (CMB) likelihoods derived from the 2018 data release. The overall approach is similar in spirit to the one retained for the 2013 and 2015 data release, with a hybrid ...
