When galaxies align: intrinsic alignments of the progenitors of elliptical galaxies in the Horizon-AGN simulation
James Bate, Nora Elisa Chisari, Sandrine Codis +5
Elliptical galaxies today appear aligned with the large-scale structure of the Universe, but it is still an open question when they acquire this alignment. Observational data is cu…
An EFT description of galaxy intrinsic alignments
Zvonimir Vlah, Nora Elisa Chisari, Fabian Schmidt
We present a general perturbative effective field theory (EFT) description of galaxy shape correlations, which are commonly known as intrinsic alignments. This rigorous approach ex…
The impact of AGN feedback on galaxy intrinsic alignments in the Horizon simulations
Adam Soussana, Nora Elisa Chisari, Sandrine Codis +7
The intrinsic correlations of galaxy shapes and orientations across the large-scale structure of the Universe are a known contaminant to weak gravitational lensing. They are known…
Astrobites as a Community-led Model for Education, Science Communication, and Accessibility in Astrophysics
Gourav Khullar, Susanna Kohler, Tarini Konchady +21
Support for early career astronomers who are just beginning to explore astronomy research is imperative to increase retention of diverse practitioners in the field. Since 2010, Ast…
Modelling baryonic feedback for survey cosmology
Nora Elisa Chisari, Alexander J. Mead, Shahab Joudaki +10
Observational cosmology in the next decade will rely on probes of the distribution of matter in the redshift range between to elucidate the nature of dark matter and dark e…
KiDS+VIKING-450 and DES-Y1 combined: Cosmology with cosmic shear
S. Joudaki, H. Hildebrandt, D. Traykova +12
We present a combined tomographic weak gravitational lensing analysis of the Kilo Degree Survey (KV450) and the Dark Energy Survey (DES-Y1). We homogenize the analysis of these two…
