The dynamical state of bars in cluster dwarf galaxies: The cases of NGC 4483 and NGC 4516
V. Cuomo, L. Morelli, J. A. L. Aguerri +13
Dwarf barred galaxies are the perfect candidates for hosting slowly-rotating bars. They are common in dense environments and they have a relatively shallow potential well, making t…
Seismic and spectroscopic analysis of 9 bright red giants observed by Kepler
H. R. Coelho, A. Miglio, T. Morel +21
Photometric time series gathered by space telescopes such as CoRoT and Kepler allow to detect solar-like oscillations in red-giant stars and to measure their global seismic constra…
Improved models for near-Earth asteroids (2100) Ra-Shalom, (3103) Eger, (12711) Tukmit & (161989) Cacus
Javier Rodríguez Rodríguez, Enrique Díez Alonso, Santiago Iglesias Álvarez +7
We present 24 new dense lightcurves of the near-Earth asteroids (3103) Eger, (161989) Cacus, (2100) Ra-Shalom and (12711) Tukmit, obtained with the Instituto Astrofísico Canarias 8…
The PAU Survey: Photometric redshift estimation in deep wide fields
D. Navarro-Gironés, E. Gaztañaga, M. Crocce +23
We present photometric redshifts (photo-) for the deep wide fields of the Physics of the Accelerating Universe Survey (PAUS), covering an area of 50 deg, for 1…
LiteBIRD Science Goals and Forecasts: Improving Sensitivity to Inflationary Gravitational Waves with Multitracer Delensing
T. Namikawa, A. I. Lonappan, C. Baccigalupi +119
We estimate the efficiency of mitigating the lensing -mode polarization, the so-called delensing, for the experiment with multiple external data sets of lensing-mass…
LiteBIRD Science Goals and Forecasts: A full-sky measurement of gravitational lensing of the CMB
A. I. Lonappan, T. Namikawa, G. Piccirilli +119
We explore the capability of measuring lensing signals in full-sky polarization maps. With a arcmin beam width and an impressively low polarization noise of $2.16\,…
