Mapping H-Excess Candidate Point Sources in the Southern Hemisphere Using S-PLUS Data
L. A. Gutiérrez-Soto, R. Lopes de Oliveira, S. Akras +18
Context. We use the Southern Photometric Local Universe Survey (S-PLUS) Fourth Data Release (DR4) to identify and classify H-excess point sources in the Southern Sky, combining…
The Main Sequence of quasars: the taming of the extremes
P. Marziani, E. Bon, N. Bon +12
The last few years have seen the confirmation of several trends associated with the quasar main sequence. The idea of a main sequence for quasars is relatively recent, and its full…
BAL effect in quasars due to source orientation
M. Sniegowska, M. H. Naddaf, M. L. Martinez-Aldama +3
We investigated a scenario where the presence of a broad absorption line (BAL) feature in quasars (QSOs) is contingent upon the line of sight being situated within an outflow cone…
Image Restoration in Non-Linear Filtering Domain using MDB approach
S. K. Satpathy, S. Panda, K. K. Nagwanshi +1
This paper proposes a new technique based on a non-linear Minmax Detector Based (MDB) filter for image restoration. The aim of image enhancement is to reconstruct the true image fr…
Potential and mass-matrix in gauged N=4 supergravity
M. de Roo, S. Panda, M. Trigiante +1
We discuss the potential and mass-matrix of gauged N=4 matter coupled supergravity for the case of six matter multiplets, extending previous work by considering the dependence on a…
Searching for Binary Black Hole Merger Emission in AGN Disks: Optical and Spectroscopic Follow-up of S240413p
P. Darc, C. R. Bom, A. Santos +7
The conditions under which binary black hole (BBH) mergers embedded in active galactic nucleus (AGN) disks produce detectable optical counterparts remain poorly constrained observa…
