ABSTRACT The Next Generation Virgo Cluster Survey (NGVS) is a program that uses the 1 deg 2 MegaCam instrument on Canada–France–Hawaii Telescope to carry out comprehensive optical imaging survey of cluster, from its core virial radius—covering total area 104 —in u * griz bandpasses. Thanks dedicated data acquisition strategy and processing pipeline, NGVS reaches point-source depth g ≈ 25.9 mag (10σ) surface brightness limit μ ∼ 29 arcsec −2 (2σ above mean sky level), thus superseding all...
The peculiar velocity of the Local Group galaxies manifested in Cosmic Microwave Background dipole is found to decompose into three dominant components. components are clearly separated because they arise on distinct spatial scales and fortuitously almost orthogonal their influences. nearest, which distinguished by a discontinuity at ~7 Mpc, arises from evacuation Void.

Cosmicflows-2 is a compilation of distances and peculiar velocities for over 8000 galaxies. Numerically the largest contributions come from luminosity–line width correlation spirals, Tully–Fisher relation (TFR), related fundamental plane E/S0 systems, but 1000 are contributed by methods that provide more accurate individual distances: Cepheid, tip red giant branch (TRGB), surface brightness fluctuation, Type Ia supernova, several miscellaneous procedures. Our collaboration making important...
The luminosity of the Tip Red Giant Branch (TRGB) provides an excellent measure galaxy distances and is easily determined in resolved images nearby galaxies observed with Hubble Space Telescope. There now a large amount archival data relevant to TRGB methodology which offers comparisons other distance estimators. Zero-point issues related scale are reviewed this paper. Consideration given metallicity dependence TRGB, transformations between HST flight systems Johnson-Cousins photometry,...
PHANGS-HST is an ultraviolet-optical imaging survey of 38 spiral galaxies within ~20 Mpc. Combined with the PHANGS-ALMA, PHANGS-MUSE surveys and other multiwavelength data, dataset will provide unprecedented look into connections between young stars, HII regions, cold molecular gas in these nearby star-forming galaxies. Accurate distances are needed to transform measured observables physical parameters (e.g., brightness luminosity, angular sizes clouds, star clusters associations). has...
The tip of the red giant branch has been used to measure distances 500 nearby galaxies with Hubble Space Telescope (HST) which are available in Color-Magnitude Diagrams and Tip Red Giant Branch (CMDs/TRGB) catalog on Extragalactic Distance Database (EDD).

With Cosmicflows-4, distances are compiled for 55,877 galaxies gathered into 38,065 groups. Eight methodologies employed, with the largest numbers coming from correlations between photometric and kinematic properties of spiral (TF) elliptical (FP).

Smaller contributions come distance estimates surface brightness fluctuations luminosities expansion rates core collapse supernovae (SNII). Cepheid...
We present an estimate of the bulk flow in a volume radii $150-200h^{-1}$Mpc using minimum variance (MV) method with data from CosmicFlows-4 (CF4) catalog. The addition new CF4 has resulted increase sphere radius $150h^{-1}$Mpc relative to CosmicFlows-3 (CF3). This less than $0.03\%$ chance occurring Standard Cosmological Model ($\Lambda$CDM) cosmic microwave background derived parameters.

The correlation between the luminosities and rotation velocities of galaxies can be used to estimate distances late-type galaxies. It is an appropriate moment reevaluate this method given great deal new information available. major improvements described here include: (1) template relations now defined by large, complete samples, (2) samples are drawn from a wide range environments, (3) photometric at B, R, I, K' bands, (4) multiband clarifies problems associated with internal reddening, (5)...
Magnitude-limited samples of spiral galaxies drawn from the Ursa Major and Pisces Clusters are used to determine their extinction properties as a function inclination. Imaging photometry is available for 87 spirals in B, R, I, K' bands. Extinction causes systematic scatter color-magnitude plots. A strong luminosity dependence found.
