Fast and accurate astronomical source deblending with Density-Peak Clustering

M. D. Lepinzan, F. Tomba, E. Romelli +2

Source deblending is a fundamental challenge for current and forthcoming astronomical surveys, where increasing source density and image depth lead to a growing number of overlappi…

Now you see me, now you don't: Deep, long-lived obscuration events of white dwarfs by dust and debris from disintegrating planetesimals

J. van Roestel, S. Bhattacharjee, J. A. Guidry +22

Transiting dust and debris around white dwarfs provide a direct view of planetary disruption. We report six previously non-variable white dwarfs that underwent single, deep obscura…

SRG/eROSITA X-ray selected cataclysmic variable candidates observed in SDSS-V DR20

J. Brink, A. D. Schwope, K. G. Pradeep +35

We report on the spectroscopic observations obtained during SDSS-V DR20 of accreting compact binaries (ACB), specifically the cataclysmic variables (CVs), that were identified as l…

Characterising EP241107a: Multiwavelength Observations of an Einstein Probe-detected Fast X-ray Transient

D. Eappachen, A. Balasubramanian, Vishwajeet Swain +12

Fast X-ray Transients (FXTs) represent a new class of highly luminous transients in soft X-rays (0.3-10 keV) associated with violent astrophysical processes. They manifest as…

1FLAT: a Firmamento-based catalog of AGN in Fermi-LAT high Galactic latitude γ-ray sources

P. Giommi, M. Doro, M. Gouvêa +15

We present a systematic reassessment of 5,062 high-Galactic latitude gamma-ray sources from the Fermi-LAT 4FGL-DR4 catalog using Firmamento, a web-based platform for multi-frequenc…

Eclipsing white dwarf from the Zwicky Transient Facility: II. Seven eclipsing double white dwarfs

J. van Roestel, K. Burdge, I. Caiazzo +15

In a systematic search for eclipsing white dwarfs using Zwicky transient facility (ZTF) data, we found seven eclipsing double white dwarfs with orbital periods ranging from 45 minu…

Cyclotron emitting magnetic white dwarfs in post common envelope binaries discovered with the Zwicky Transient Facility

J. van Roestel, A. C. Rodriguez, P. Szkody +20

We present the discovery of 14 new (and recovery of 4 known) low accretion rate magnetic white dwarfs in post-common envelope binaries that emit strong cyclotron emission using the…

Compact white-dwarf binaries in the combined SRG/eROSITA/SDSS eFEDS survey

A. Schwope, J. Kurpas, P. Baecke +22

Aims. Compact white-dwarf binaries are selected from spectra obtained in the early SDSS-V plate program. A dedicated set of SDSS plate observations were carried out in the eFEDS fi…
