Resolved Dust-Gas-Metallicity relations in nearby spiral galaxies

Vidhi Tailor, Viviana Casasola, Francesco Calura +17

Context: Understanding the interstellar medium (ISM) requires high-resolution, multi-component mapping to capture its complex physical structure. Nearby spiral galaxies, with their…

Metal-THINGS: gas metallicity gradients in nearby galaxies

Guillermo Valé, Maritza A. Lara-López, Mabel Valerdi +13

This paper explores the gas metallicity gradients in a sample of 25 nearby galaxies using new Integral Field Spectroscopy observations from the Metal-THINGS survey. We derive and s…

2D Surface Brightness Modelling of Large 2MASS Galaxies II: The Role of Classical Bulges and Pseudobulges on Galaxy Scaling Relations and its implication for Supermassive Black Hole Formation

Emmanuel Ríos-López, Omar López-Cruz, Christopher Añorve +3

We have generated 2D-multicomponent surface brightness (SB) modelling for 100 galaxies in the Large Galaxy Atlas (LGA) together with 19 nearby cD galaxies using the near-infrared (…

Direct estimates of nitrogen abundance for Seyfert 2 nuclei

O. L. Dors, M. V. Cardaci, G. F. Hägele +10

We derive the nitrogen and oxygen abundances in the Narrow Line Regions (NLRs) of a sample of 38 local () Seyfert~2 nuclei. For that, we consider narrow optical emis…

Metal-THINGS: a panchromatic analysis of the local scaling relationships of the dwarf irregular galaxy NGC 1569

L. E. Garduño, J. Zaragoza-Cardiel, M. A. Lara-López +12

We investigate several panchromatic scaling relations (SRs) for the dwarf irregular galaxy NGC 1569 using IFU data from the Metal-THINGS Survey. Among the spatially resolved proper…

One hundred optical emission lines of molecular hydrogen from a low-metallicity photodissociation region

William J. Henney, Mabel Valerdi

We report the detection of a rich spectrum of more than one hundred optical emission lines of vibrationally hot molecular hydrogen (H2) from the photodissociation region (PDR) arou…
