A possible explanation for the increase in the mass\u0000function can be the presence of a local maximum (bump) in the power spectrum of\u0000density perturbations on the corresponding scale. In this paper, it is shown\u0000that simultaneously with the growth of the mass function, galaxies from the\u0000bump region must have a higher density (compactness) compared to cosmological\u0000models without a bump. These more compact galaxies have been partially included\u0000in larger galaxies and have been subjected to tidal gravitational disruption.\u0000They have been less destructed than ``ordinary'' galaxies of the same mass, and\u0000some of them could survive to $z = 0$ and persist on the periphery of some\u0000galaxies. The formation and evolution of compact halos in a cube with a volume\u0000of $(47 ,text{Mpc})^3$ with $(1024)^3$ dark matter particles in the redshift\u0000range from 120 to 0 have been numerically simulated and observational\u0000implications of the presence of such galaxies in the current Universe have been\u0000discussed.","PeriodicalId":501207,"journal":{"name":"arXiv - PHYS - Cosmology and Nongalactic Astrophysics","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142192644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examine a class of such spacetimes that maintain\u0000homogeneity but break isotropy through their underlying local spatial\u0000geometries. These spacetimes are endowed with one of five anisotropic model\u0000geometries of Thurston's geometrization theorem, and their evolution is sourced\u0000with perfect fluid dust and cosmological constant. We show that the background\u0000evolution of these spacetimes induces fluctuations in the observed cosmic\u0000microwave background (CMB) temperature with amplitudes coupled to the curvature\u0000parameter $Omega_K$. In order for these fluctuations to be compatible with the\u0000observed CMB angular power spectrum, we find $|Omega_K| lesssim 10^{-5}$ is\u0000required in all five geometries, with two geometries requiring $|Omega_K|\u0000lesssim 10^{-10}$.

Many techniques have been developed to\u0000model this connection, from Halo Occupation Distribution (HOD) to empirical and\u0000semi-analytic models to hydrodynamic. Hydrodynamic simulations can incorporate\u0000more detailed astrophysical processes but are computationally expensive; HODs,\u0000on the other hand, are computationally cheap but have limited accuracy. In this\u0000work, we present NeHOD, a generative framework based on variational diffusion\u0000model and Transformer, for painting galaxies/subhalos on top of DM with an\u0000accuracy of hydrodynamic simulations but at a computational cost similar to\u0000HOD. By modeling galaxies/subhalos as point clouds, instead of binning or\u0000voxelization, we can resolve small spatial scales down to the resolution of the\u0000simulations. For each halo, NeHOD predicts the positions, velocities, masses,\u0000and concentrations of its central and satellite galaxies. We train NeHOD on the\u0000TNG-Warm DM suite of the DREAMS project, which consists of 1024 high-resolution\u0000zoom-in hydrodynamic simulations of Milky Way-mass halos with varying warm DM\u0000mass and astrophysical parameters. We show that our model captures the complex\u0000relationships between subhalo properties as a function of the simulation\u0000parameters, including the mass functions, stellar-halo mass relations,\u0000concentration-mass relations, and spatial clustering. Our method can be used\u0000for a large variety of downstream applications, from galaxy clustering to\u0000strong lensing studies.","PeriodicalId":501207,"journal":{"name":"arXiv - PHYS - Cosmology and Nongalactic Astrophysics","volume":"49 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142192638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use the\u0000DEMNUni-Cov $N$-body simulations to assess how well the WL mass probes the true\u0000halo mass, and, then, how well WL masses can be recovered in the presence of\u0000measurement uncertainties. We consider different halo mass density models,\u0000priors, and mass point estimates. WL mass differs from true mass due to, e.g.,\u0000the intrinsic ellipticity of sources, correlated or uncorrelated matter and\u0000large-scale structure, halo triaxiality and orientation, and merging or\u0000irregular morphology. In an ideal scenario without observational or measurement\u0000errors, the maximum likelihood estimator is the most accurate, with WL masses\u0000biased low by $langle b_M rangle = -14.6 pm 1.7 , %$ on average over the\u0000full range $M_text{200c} > 5 times 10^{13} , M_odot$ and $z < 1$. Due to\u0000the stabilising effect of the prior, the biweight, mean, and median estimates\u0000are more precise. The scatter decreases with increasing mass and informative\u0000priors significantly reduce the scatter. Halo mass density profiles with a\u0000truncation provide better fits to the lensing signal, while the accuracy and\u0000precision are not significantly affected. We further investigate the impact of\u0000additional sources of systematic uncertainty on the WL mass, namely the impact\u0000of photometric redshift uncertainties and source selection, the expected\u0000performance of Euclid cluster detection algorithms, and the presence of masks.\u0000Taken in isolation, we find that the largest effect is induced by\u0000non-conservative source selection. This effect can be mostly removed with a\u0000robust selection.
