The Hubble Rate Trouble: An Effective Field Theory of Dark Matter
Alvaro S. de Jesus, Nelson Pinto-Neto, Farinaldo S. Queiroz +2
The Hubble constant inferred from the 6-parameter fit to the CMB power spectrum conflicts with the value obtained from direct measurements via type Ia supernova and Cepheids observ…
The Dark Energy Survey Year 3 and eBOSS: constraining galaxy intrinsic alignments across luminosity and colour space
S. Samuroff, R. Mandelbaum, J. Blazek +104
We present direct constraints on galaxy intrinsic alignments using the Dark Energy Survey Year 3 (DES Y3), the Extended Baryon Oscillation Spectroscopic Survey (eBOSS) and its prec…
Seeking the growth of the first black hole seeds with JWST
Alessandro Trinca, Raffaella Schneider, Roberto Maiolino +3
In this paper we provide predictions for the BH population that would be observable with planned JWST surveys at . We base our study on the recently developed Cosmi…
Aberration of gravitational waveforms by peculiar velocity
Camille Bonvin, Giulia Cusin, Cyril Pitrou +3
One key prediction of General Relativity is that gravitational waves are emitted with a pure spin-2 polarisation. Any extra polarisation mode, spin-1 or spin-0, is consequently con…
Reionization with star-forming galaxies: insights from the Low-z Lyman Continuum Survey
Maxime Trebitsch, Pratika Dayal, John Chisholm +18
The fraction of ionizing photons escaping from galaxies, , is at the same time a crucial parameter in modelling reionization and a very poorly known quantity, especially a…
Discovery of TOI-1260d and the characterisation of the multi-planet system
Kristine W. F. Lam, J. Cabrera, M. J. Hooton +83
We report the discovery of a third planet transiting the star TOI-1260, previously known to host two transiting sub-Neptune planets with orbital periods of 3.127 and 7.493 days, re…
Emission-line properties of IllustrisTNG galaxies: from local diagnostic diagrams to high-redshift predictions for JWST
Michaela Hirschmann, Stephane Charlot, Anna Feltre +8
We compute synthetic, rest-frame optical and ultraviolet (UV) emission-line properties of galaxy populations at redshifts from z0 to z=8 in a full cosmological framework.…
The Art of Measuring Physical Parameters in Galaxies: A Critical Assessment of Spectral Energy Distribution Fitting Techniques
Camilla Pacifici, Kartheik G. Iyer, Bahram Mobasher +52
The study of galaxy evolution hinges on our ability to interpret multi-wavelength galaxy observations in terms of their physical properties. To do this, we rely on spectral energy…
Low-Surface-Brightness Galaxies are missing in the observed Stellar Mass Function
Juhan Kim, Jaehyun Lee, Clotilde Laigle +8
We investigate the impact of the surface brightness (SB) limit on the galaxy stellar mass functions (GSMFs) using mock surveys generated from the Horizon Run 5 (HR5) simulation. We…
Off-centre supermassive black holes in bright central galaxies
Aline Chu, Pierre Boldrini, Joe Silk
Supermassive black holes (SMBHs) are believed to reside at the centre of massive galaxies such as brightest cluster galaxies (BCGs). However, as BCGs experienced numerous galaxy me…
Ambiguous power spectrum from a quantum bounce
Jaime de Cabo Martin, Przemysław Małkiewicz, Patrick Peter
A quantum cosmological bouncing model may exhibit an ambiguity stemming from the nonclassical nature of the background evolution: two classically equivalent theories can produce tw…
JWST UNCOVER: Extremely red and compact object at triply imaged by Abell 2744
Lukas J. Furtak, Adi Zitrin, Adèle Plat +29
Recent JWST/NIRCam imaging taken for the ultra-deep UNCOVER program reveals a very red dropout object at , triply imaged by the galaxy cluster Abell 274…
Massive galaxy formation caught in action at z~5 with JWST
Shuowen Jin, Nikolaj B. Sillassen, Georgios E. Magdis +13
We report the discovery of a compact group of galaxies, CGG-z5, at z~5.2 in the EGS field covered by the JWST/CEERS survey. CGG-z5 was selected as the highest overdensity of galaxi…
Machine-learning cosmology from void properties
Bonny Y. Wang, Alice Pisani, Francisco Villaescusa-Navarro +1
Cosmic voids are the largest and most underdense structures in the Universe. Their properties have been shown to encode precious information about the laws and constituents of the…
Massive black hole assembly in nuclear star clusters
Konstantinos Kritos, Emanuele Berti, Joseph Silk
Nuclear star clusters, which fragment into metal-poor stars in situ at the centers of protogalaxies, provide ideal environments for the formation of intermediate-mass black holes w…
A Measurement of the CMB Temperature Power Spectrum and Constraints on Cosmology from the SPT-3G 2018 TT/TE/EE Data Set
L. Balkenhol, D. Dutcher, A. Spurio Mancini +84
We present a sample-variance-limited measurement of the temperature power spectrum () of the cosmic microwave background (CMB) using observations of a $\sim\! 1500 \,\mathrm{de…
What if young z>9 JWST galaxies hosted massive black holes?
Marta Volonteri, Melanie Habouzit, Monica Colpi
JWST is discovering star forming `candidate' galaxies with photometric redshifts and little attenuation. We model presumptive massive black holes (MBHs) in such galaxies and…
Identification and properties of intense star-forming galaxies at redshifts z>10
B. E. Robertson, S. Tacchella, B. D. Johnson +53
Surveys with James Webb Space Telescope (JWST) have discovered candidate galaxies in the first 400 Myr of cosmic time. Preliminary indications have suggested these candidate galaxi…

Non-local contribution from small scales in galaxy-galaxy lensing: Comparison of mitigation schemes
J. Prat, G. Zacharegkas, Y. Park +112
Recent cosmological analyses with large-scale structure and weak lensing measurements, usually referred to as 32pt, had to discard a lot of signal-to-noise from small scale…
A non-parametric approach to the relation between the halo mass function and internal dark matter structure of haloes
T. R. G. Richardson, P. -S. Corasaniti
Context. Galaxy cluster masses are usually defined as the mass within a spherical region enclosing a given matter overdensity (in units of the critical density). Converting masses…
COSMOS2020: The Galaxy Stellar Mass Function: the assembly and star formation cessation of galaxies at
J. R. Weaver, I. Davidzon, S. Toft +30
