We compute and investigate four types of imprint a stochastic background primordial magnetic fields (PMFs) on the cosmic microwave (CMB) anisotropies: impact PMFs CMB spectra; effect polarization induced by Faraday rotation; ionization history; magnetically-induced non-Gaussianities; breaking statistical isotropy. Overall, Planck data constrain amplitude to less than few nanogauss. In particular, individual limits coming from analysis angular power spectra, using likelihood, are...
We present the results on study of global and local M-Z relation based first data available from CALIFA survey (150 galaxies). This provides integral field spectroscopy complete optical extent each galaxy (up to 2-3 effective radii), with enough resolution separate individual HII regions and/or aggregations. Nearly $\sim$3000 have been detected. The spectra cover wavelength range between [OII]3727 [SII]6731, a sufficient signal-to-noise derive oxygen abundance star-formation rate associated...
We present the first public data release of CALIFA survey. It consists science-grade optical datacubes for 100 eventually 600 nearby (0.005<z<0.03) galaxies, obtained with integral-field spectrograph PMAS/PPak mounted on 3.5m telescope at Calar Alto observatory. The galaxies in DR1 already cover a wide range properties color-magnitude space, morphological type, stellar mass, and gas ionization conditions. This offers potential to tackle variety open questions galaxy evolution using spatially...
This paper describes the Second Public Data Release (DR2) of Calar Alto Legacy Integral Field Area (CALIFA) survey. The data for 200 objects are made public, including 100 galaxies First (DR1). were obtained with integral-field spectrograph PMAS/PPak mounted on 3.5 m telescope at observatory. Two different spectral setups available each galaxy, (i) a low-resolution V500 setup covering wavelength range 3745-7500 \AA\ resolution 6.0 (FWHM), and (ii) medium-resolution V1200 3650-4840 2.3...
We measured the gas abundance profiles in a sample of 122 face-on spiral galaxies observed by CALIFA survey and included all spaxels whose line emission was consistent with star formation. This type analysis allowed us to improve statistics respect previous studies, properly estimate oxygen distribution across entire disc distance up 3-4 effective radii (r$_e$). confirm results obtained from classical HII region analysis. In addition general negative gradient, an outer flattening can be...
We present a two-dimensional multi-component photometric decomposition of 404 galaxies from the CALIFA Data Release 3. They represent all possible with no clear signs interaction and not strongly inclined in final data release. Galaxies are modelled g, r, i SDSS images including, when appropriate, nuclear point source, bulge, bar, an exponential or broken disc component. use human-supervised approach to determine optimal number structures be included fit. The dataset, including parameters...
Context. The mass-size relation is a fundamental galaxy scaling that intrinsically linked to formation and evolution. physical processes involved in growth leave their particular imprint on the between stellar or total mass size. Aims. We aim explore effect of large-scale environment using samples selection added-value products from Calar Alto Void Integral-field Treasury surveY (CAVITY) collaboration. Methods. analysed Petrosian R50 R90 radii SDSS DR16 images sample ≈14 000 galaxies...
We study the stellar properties of 44 face-on spiral galaxies from Calar Alto Legacy Integral Field Area survey via full spectrum fitting techniques. compare age profiles with surface brightness distribution in order to highlight differences between profile types (type I, exponential profile; and II, down-bending profile). observe an upturn ("U-shape") for 17 out these reliable information up their outer parts. This "U-shape" is not a unique feature type II but can be observed I as well....
We present optical integral field spectroscopy (IFS) observations of the Mice, a major merger between two massive (≳1011 M⊙) gas-rich spirals NGC 4676A and B, observed first passage final coalescence. The spectra provide stellar gas kinematics, ionised properties, population diagnostics, over full extent both galaxies with ~1.6 kpc spatial resolution. Mice perfect case study that highlights importance IFS data for improving our understanding local galaxies. impact on kinematics stars has...
Context. Accurate star formation histories (SFHs) of galaxies are fundamental for understanding the build-up their stellar content. However, most accurate SFHs – those obtained from colour-magnitude diagrams (CMDs) resolved stars reaching oldest main-sequence turnoffs (oMSTO) presently limited to a few systems in Local Group. It is therefore crucial determine reliability and range applicability derived integrated light spectroscopy, as this affects our unresolved low high redshift.
We estimate the current extinction-corrected H$\alpha$ star formation rate (SFR) of different morphological components that shape galaxies (bulges, bars, and disks). use a multi-component photometric decomposition based on SDSS imaging to CALIFA Integral Field Spectroscopy datacubes for sample 219 galaxies. This analysis reveals an enhancement central SFR specific (sSFR $=$ SFR/$M_{\star}$) in barred Along Main Sequence, we find more massive total have undergone efficient suppression...
This work investigates the effect of aperture size on derived galaxy properties for which we have spatially-resolved optical spectra. We focus some indicators star formation activity and dust attenuation spiral galaxies that been widely used in previous evolution. investigated 104 from CALIFA survey 2D spectroscopy with complete spatial coverage is available. From 3D cubes growth curves most conspicuous Balmer emission lines (Hα, Hβ) circular apertures different radii centered at galaxy’s...
We present a galaxy classification system for 238 (E1–Sdm) CALIFA (Calar Alto Legacy Integral Field Area) galaxies based on the shapes and amplitudes of their circular velocity curves (CVCs). infer CVCs from de-projected surface brightness galaxies, after scaling by constant mass-to-light ratio stellar dynamics – solving axisymmetric Jeans equations via fitting second moment |$V_{\mathrm{rms}}=\sqrt{V^2+\sigma ^2}$| kinematics. use principal component analysis (PCA) applied to CVC find...
The Universe is shaped as a web-like structure, formed by clusters, filaments, and walls that leave large volumes in between named voids. Galaxies voids have been found to be of later type, bluer, less massive, slower evolution than galaxies denser environments (filaments walls). However, the effect void environment on their stellar population properties still unclear. We aim address this question using 118 optical integral field unit datacubes from Calar Alto Void Integral-field Treasury...
We have learnt in the last decades that majority of galaxies belong to high density regions interconnected a sponge-like fashion. This large-scale structure is characterised by clusters, filaments, and walls, where most concentrate, but also under-dense called voids. The void within represent an ideal place for study galaxy formation evolution, as they are largely unaffected complex physical processes transform high-density environments. may hold key answer current challenges Lambda CDM...
We study, for the first time in a statistically significant and well-defined sample, relation between outer-disk ionized-gas metallicity gradients presence of breaks surface brightness profiles disk galaxies.
