Search for LBVs in the Local Volume galaxies: study of two stars in NGC 1156 [PDF]

open access: yes, 2022
We continue the search for luminous blue variables (LBVs) in Local Volume galaxies in order to study their fundamental parameters. In this paper, we report the discovery of two new LBVs in the dwarf irregular galaxy NGC 1156.

A LINK TO THE PAST: USING MARKOV CHAIN MONTE CARLO FITTING TO CONSTRAIN FUNDAMENTAL PARAMETERS OF HIGH-REDSHIFT GALAXIES [PDF]

open access: yes, 2011
We have developed a new method for fitting spectral energy distributions (SEDs) to identify and constrain the physical properties of high-redshift (4 < z < 8) galaxies.

Physical parameters of red supergiants in dwarf irregular galaxies in the Local Group [PDF]

open access: yesAstronomy & Astrophysics, 2019
Context. Increasing the statistics of evolved massive stars in the Local Group enables investigating their evolution at different metallicities. During the late stages of stellar evolution, the physics of some phenomena, such as episodic and systematic ...

Study of star-forming galaxies in SDSS up to redshift 0.4 II. Evolution from the fundamental parameters: mass, metallicity & SFR [PDF]

open access: yes, 2010
To understand the formation and evolution of galaxies, it is important to have a full comprehension of the role played by the metallicity, star formation rate (SFR), morphology, and color.

Low gas-phase metallicities of ultraluminous infrared galaxies are a result of dust obscuration [PDF]

open access: yesNature Astronomy, 2021
Optical spectroscopic measurements show that gas in dusty, starbursting galaxies known as ultraluminous infrared galaxies (ULIRGs) in the local Universe has a significantly lower metal content than that of gas in star-forming galaxies with similar masses.

Possible effects of hybrid gravity on stellar kinematics in elliptical galaxies [PDF]

open access: yesEuropean Physical Journal D : Atomic, Molecular and Optical Physics, 2021
We use the Fundamental Plane of Elliptical Galaxies to constrain the so-called Hybrid Gravity, a modified theory of gravity where General Relativity is improved by further degrees of freedom of metric-affine Palatini formalism of f(R)\documentclass[12pt]{

An orientation bias in observations of submillimetre galaxies [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2021
Recent high-resolution interferometric images of submillimetre galaxies (SMGs) reveal fascinatingly complex morphologies. This raises a number of questions: how does the relative orientation of a galaxy affect its observed submillimetre emission, and ...

Subgalactic Scaling Relations with T e-based Metallicities of Low-metallicity Regions in Galaxies: Metal-poor Gas Inflow May Have Important Effects? [PDF]

open access: yesAstrophysical Journal, 2021
The scaling relationship is a fundamental probe of the evolution of galaxies. Using the integral field spectroscopic data from the Mapping Nearby Galaxies at Apache Point Observatory survey, we select 1698 spaxels with a significant detection of the ...

The KMOS Cluster Survey (KCS). III. Fundamental Plane of Cluster Galaxies at z ≃ 1.80 in JKCS 041 [PDF]

open access: yes, 2017
We present data for 16 galaxies in the overdensity JKCS 041 at as part of the K-band Multi-Object Spectrograph (KMOS) Cluster Survey (KCS). With 20 hr integrations, we have obtained deep absorption-line spectra from which we derived velocity dispersions ...

Targeted decrease of portal hepatic pressure gradient improves ascites control after TIPS

open access: yesHepatology, EarlyView., 2022
The river diagram demonstrates that after transjugular intrahepatic portosystemic shunt insertion (TIPS) the majority of patients without ascites and 50% of the patients with ascites detectable at ultrasound, show the best response in the long term follow‐up.
