Baryonic effects on the detectability of annihilation radiation from dark matter subhaloes around the Milky Way
Robert J J Grand, Simon D M White
We use six, high-resolution CDM simulations of galaxy formation to study how emission from dark matter annihilation is affected by baryonic processes. These simulations produce…
The impact of Solar wind variability on pulsar timing
C. Tiburzi, G. M. Shaifullah, C. G. Bassa +22
High-precision pulsar timing requires accurate corrections for dispersive delays of radio waves, parametrized by the dispersion measure (DM), particularly if these delays are varia…
The KMOS Survey: Investigating the Origin of the Elevated Electron Densities in Star-Forming Galaxies at
Rebecca L. Davies, N. M. Förster Schreiber, R. Genzel +24
We investigate what drives the redshift evolution of the typical electron density () in star-forming galaxies, using a sample of 140 galaxies drawn primarily from KMOS$^{\rm 3…
Luminous Red Nova AT 2019zhd, a new merger in M 31
A. Pastorello, M. Fraser, G. Valerin +20
We present the follow-up campaign of the luminous red nova (LRN) AT~2019zhd, the third event of this class observed in M 31. The object was followed by several sky surveys for abou…
Molecular hydrogen in IllustrisTNG galaxies: carefully comparing signatures of environment with local CO & SFR data
Adam R. H. Stevens, Claudia del P. Lagos, Luca Cortese +7
We examine how the post-processed content of molecular hydrogen (H) in galaxies from the TNG100 cosmological, hydrodynamic simulation changes with environment at , ass…
Detection of large-scale X-ray bubbles in the Milky Way halo
P. Predehl, R. A. Sunyaev, W. Becker +25
The halo of the Milky Way provides a laboratory to study the properties of the shocked hot gas that is predicted by models of galaxy formation. There is observational evidence of e…
Calibrating Core Overshooting Parameters With Two-dimensional Hydrodynamical Simulations
Johann Higl, Ewald Mueller, Achim Weiss
The extent of mixed regions around convective zones is one of the biggest uncertainties in stellar evolution. 1D overshooting descriptions introduce a free parameter () tha…
A search for dust and molecular gas in enormous Ly nebulae at
Roberto Decarli, Fabrizio Arrigoni-Battaia, Joseph F. Hennawi +3
Enormous Ly nebulae, extending over 300-500\,kpc around quasars, represent the pinnacle of galaxy and cluster formation. Here we present IRAM Plateau de Bure Interferometer obse…
Galaxies within galaxies in the TIMER survey: stellar populations of inner bars are scaled replicas of main bars
Adrian Bittner, Adriana de Lorenzo-Cáceres, Dimitri A. Gadotti +11
Inner bars are frequent structures in the local Universe and thought to substantially influence the nuclear regions of disc galaxies. In this study we explore the structure and dyn…
Galaxy shape statistics in the effective field theory
Zvonimir Vlah, Nora Elisa Chisari, Fabian Schmidt
Intrinsic galaxy alignments yield an important contribution to the observed statistics of galaxy shapes. The general bias expansion for galaxy sizes and shapes in three dimensions…
Insight-HXMT observations of a possible fast transition from jet to wind dominated state during a huge flare of GRS~1915+105
L. D. Kong, S. Zhang, Y. P. Chen +92
We present the analysis of the brightest flare that was recorded in the \emph{Insight}-HMXT data set, in a broad energy range (2200 keV) from the microquasar GRS~1915+105 during…
Gaia Early Data Release 3: The Gaia Catalogue of Nearby Stars
Gaia Collaboration, R. L. Smart, L. M. Sarro +420
We produce a clean and well-characterised catalogue of objects within 100\,pc of the Sun from the \G\ Early Data Release 3. We characterise the catalogue through comparisons to the…
Gaia Early Data Release 3: Acceleration of the solar system from Gaia astrometry
Gaia Collaboration, S. A. Klioner, F. Mignard +414
Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quali…
A first-principle simulation of blast wave emergence at the photosphere of a neutron star merger
Christoffer Lundman, Andrei Beloborodov
We present the first ab initio simulation of a radiation-mediated shock emerging at the photosphere of a relativistic outflow. The simulation is performed using our code radshock t…
Populations of super-soft X-ray sources in galaxies of different morphological types
I. Galiullin, M. Gilfanov
We study populations of soft and super-soft X-ray sources in nearby galaxies of various morphological types with the special emphasis on characterizing populations of stable nuclea…
