HI Observations of Baryon-Dominated Dwarf Galaxy Candidates
Atharva Mirashi, Abhinav Narayan, K. Keerthi +7
We present resolved HI observations of six dwarf galaxies drawn from a sample of baryon-dominated dwarf galaxy (BDDG) candidates previously identified using global HI spectra from…
MeerKAT radio continuum imaging of nearby star-forming spirals in the NGC 6221, NGC 3256/3263, and NGC 2434 galaxy groups
J. Saponara, B. S. Koribalski, J. English +1
Context. We present high-resolution MeerKAT 1.3 GHz radio continuum images of star-forming spirals in the nearby galaxy groups around NGC 6221, NGC 3256/3263 and NGC 2434. This sam…
High resolution radio analysis of the starburst galaxy NGC 4527: signatures of an AGN core
C. A. Galante, G. E. Romero, J. Saponara +1
NGC 4527 is a nearby edge-on spiral galaxy with both starburst and AGN features, hosting a LINER nucleus. We present a radio study of the large-scale structure and nuclear region o…
Radio study of the colliding wind binary HD93129A near periastron and its surroundings
Paula Benaglia, Santiago del Palacio, Juliana Saponara +3
HD93129A is an O+O stellar system whose CWR has been mapped by high angular resolution observations at cm wavelengths. The synchrotron nature of the radio emission confirms its par…
Search for extraplanar radio emission in a sample of edge-on starburst galaxies
C. A. Galante, J. Saponara, G. E. Romero +1
The intense star formation in starburst galaxies results in the formation of intense winds that sweep matter up to several kpc out of the galactic plane. These winds can be detecte…
Search for radio halos in starburst galaxies
C. A. Galante, J. Saponara, G. E. Romero +1
Starburst galaxies are undergoing intense episodes of star formation. In these galaxies, gas is ejected into the surrounding environment through winds created by the effect of hot…
Disentangling the nature of the prototype radio weak BL Lac: Contemporaneous multifrequency observations of WISE J141046.00 + 740511.2
E. J. Marchesini, V. Reynaldi, F. Vieyro +13
Context. The gamma-ray emitting source WISE J141046.00+740511.2 has been associated with a Fermi-LAT detection by crossmatching with Swift/XRT data. It has shown all the canonical…
Investigation of the double-lobed sources of the Cygnus constellation core
J. Saponara, P. Benaglia, I. Andruchow +2
We present a collection of double-lobed sources towards a 20 sq deg area of the Cygnus region at the northern sky, observed at 325 and 610~MHz with the Giant Metrewave Radio Telesc…
The Fourcade-Figueroa galaxy: a clearly disrupted superthin edge-on galaxy
J. Saponara, P. Kamphuis, B. S. Koribalski +1
Studies of the stellar and the HI gas kinematics in dwarf and Low Surface Brightness (LSB) galaxies are essential for deriving constraints on their dark matter distribution. Moreov…
The Fornax Cluster through S-PLUS
A. V. Smith Castelli, C. Mendes de Oliveira, F. Herpich +25
The Southern Photometric Local Universe Survey (S-PLUS) aims to map 9300 deg of the Southern sky using the Javalambre filter system of 12 optical bands, 5 Sloan-like…
New HI observations of KK 69. Is KK 69 a dwarf galaxy in transition?
J. Saponara, B. S. Koribalski, N. N. Patra +1
We present new HI data of the dwarf galaxy KK 69, obtained with the Giant Metrewave Radio Telescope (GMRT) with a signal-to-noise ratio that almost double previous observations. We…
HI debris in the IC 1459 galaxy group
Juliana Saponara, Bärbel S. Koribalski, Paula Benaglia +1
We present HI synthesis imaging of the giant elliptical galaxy IC 1459 and its surroundings with the Australia Telescope Compact Array (ATCA). Our search for extended HI emission r…
