We present validation tests of emulator-based halo model method for cosmological parameter inference, assuming hypothetical measurements of the projected correlation function of ga…
Searching for active low-mass stars in CMa star-forming region: multi-band photometry with T80S
J. Gregorio-Hetem, F. Navarete, A. Hetem +10
An exotic environment surrounds the young stellar groups associated with the Canis Major (CMa) OB1/R1 region, which probably was formed under feedback from at least three supernova…
Non-perturbative halo clustering from cosmological density peaks
Tobias Baldauf, Sandrine Codis, Vincent Desjacques +1
Associating the formation sites of haloes with the maxima of the smoothed linear density field, we present non-perturbative predictions for the Lagrangian and evolved halo correlat…
Phase-space structure of protohalos: Vlasov versus Particle-Mesh
Stéphane Colombi
The phase-space structure of primordial dark matter halos is revisited using cosmological simulations with three sine waves and Cold Dark Matter (CDM) initial conditions. The simul…
Census of R Coronae Borealis stars I: Infrared light curves from Palomar Gattini IR
Viraj R. Karambelkar, Mansi M. Kasliwal, Patrick Tisserand +16
We are undertaking the first systematic infrared (IR) census of R Coronae Borealis (RCB) stars in the Milky Way, beginning with IR light curves from the Palomar Gattini IR (PGIR) s…
Neutron stars as probes of dark matter
M. Ángeles Pérez-García, J. Silk
Neutron Stars (NSs) are compact stellar objects that are stable solutions in General Relativity. Their internal structure is usually described using an equation of state that invol…
A fast semi-discrete optimal transport algorithm for a unique reconstruction of the early Universe
Bruno Lévy, Roya Mohayaee, Sebastian von Hausegger
We leverage powerful mathematical tools stemming from optimal transport theory and transform them into an efficient algorithm to reconstruct the fluctuations of the primordial dens…
Dark Energy Survey Year 3 Results: Clustering Redshifts -- Calibration of the Weak Lensing Source Redshift Distributions with redMaGiC and BOSS/eBOSS
M. Gatti, G. Giannini, G. M. Bernstein +94
We present the calibration of the Dark Energy Survey Year 3 (DES Y3) weak lensing source galaxy redshift distributions from clustering measurements. In particular, we cross-…
DRAGraces: A pipeline for the GRACES high-resolution spectrograph at Gemini
André-Nicolas Chené, Shunyuan Mao, Michael Lundquist +2
This paper describes the software DRAGraces (Data Reduction and Analysis for GRACES), which is a pipeline reducing spectra from GRACES (Gemini Remote Access to the CFHT ESPaDOnS Sp…
Discovery of a damped Ly galaxy at z 3 towards the quasar SDSS J011852+040644
Ravi Joshi, Michele Fumagalli, Raghunathan Srianand +11
We report the detection of the host galaxy of a damped Ly system (DLA) with log N(HI) = at towards the background quasar SDSS…
Constraining the quasar radio-loud fraction at with deep radio observations
Yuanqi Liu, Ran Wang, Emmanuel Momjian +8
We carry out a series of deep Karl G. Jansky Very Large Array (VLA) S-band observations of a sample of 21 quasars at . The new observations expand the searches of radio con…
Fast radio burst repeaters produced via Kozai-Lidov feeding of neutron stars in binary systems
Valentin Decoene, Kumiko Kotera, Joseph Silk
Neutron stars are likely surrounded by gas, debris, and asteroid belts. Kozai-Lidov perturbations, induced by a distant, but gravitationally bound companion, can trigger the infall…
The Dark Energy Survey Supernova Program: Modelling selection efficiency and observed core collapse supernova contamination
M. Vincenzi, M. Sullivan, O. Graur +79
The analysis of current and future cosmological surveys of type Ia supernovae (SNe Ia) at high-redshift depends on the accurate photometric classification of the SN events detected…
Star-Gas Misalignment in Galaxies: II. Origins Found from the Horizon-AGN Simulation
Donghyeon J. Khim, Sukyoung K. Yi, Christophe Pichon +5
There have been many studies aiming to reveal the origins of the star-gas misalignment found in galaxies, but there still is a lack of understanding of the contribution from each f…
The properties and environment of very young galaxies in the local Universe
M. Trevisan, G. A. Mamon, T. X. Thuan +3
In the local Universe, there is a handful of dwarf compact star-forming galaxies with extremely low oxygen abundances. It has been proposed that they are young, having formed a lar…
Boosting small-scale structure via primordial black holes and implications for sub-GeV dark matter annihilation
Kenji Kadota, Joseph Silk
We explore the possibility that the annihilation of dark matter (DM) is boosted due to enhanced substructure in the presence of primordial black holes (PBHs) which constitute a sub…
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…
