Two Predicted, Concentric Nova Shells Surround the Prototype Dwarf Nova U Geminorum
Michael M. Shara, Kenneth M. Lanzetta, Aayushi Doshi +7
In the 170 years since its discovery, U Gem has been intensively studied as the prototypical cataclysmic binary star. Its massive white dwarf (WD) (~ 1.2 Msun) is cannibalizing its…
The cosmic web's Lyman- glow at ; hydrodynamic models, dust, and wide-field, narrow-band detection
Oleksii Sokoliuk, John K. Webb, Kenneth M. Lanzetta +12
The diffuse Lyman- glow of the cosmic web has long been predicted but has so far eluded direct detection over cosmologically significant volumes. We construct synthetic Lyman-$α…
A 70 pc-Diameter Nova Super-remnant Surrounding the Recurrent Nova RS Ophiuchi
Michael M. Shara, Kenneth M. Lanzetta, Alexandra Masegian +9
Recurrent novae undergo thermonuclear-powered eruptions separated by less than 100 years, enabled by subgiant or red giant donors transferring hydrogen-rich matter at very high rat…
Direct Images of the Cosmic Web of Intergalactic and Circumgalactic Gas in the Distant Universe
Kenneth M. Lanzetta, Stefan Gromoll, Michael M. Shara +5
Most of the baryonic matter of the Universe resides in a highly-ionized gaseous intergalactic medium. This gas flows along dark-matter filaments toward galaxy superclusters, cluste…
The Newly Discovered Nova Super-Remnant Surrounding Recurrent Nova T Coronae Borealis: Will it Light Up During the Coming Eruption?
Michael M. Shara, Kenneth M. Lanzetta, Alexandra Masegian +7
A century or less separates the thermonuclear-powered eruptions of recurrent novae in the hydrogen-rich envelopes of massive white dwarfs. The colliding ejecta of successive recurr…
Introducing the Condor Array Telescope. VI. Discovery of Extensive Ionized Gaseous Filaments of the Cosmic Web in the Direction of the M81 Group
Kenneth M. Lanzetta, Stefan Gromoll, Michael M. Shara +3
We used the Condor Array Telescope to obtain deep imaging observations through luminance broad-band and He II, [O III], He I, H, [N II], and [S II] narrow-band filters of an ext…
Introducing the Condor Array Telescope. V. Deep Broad- and Narrow-Band Imaging Observations of the M81 Group
Kenneth M. Lanzetta, Stefan Gromoll, Michael M. Shara +3
We used the Condor Array Telescope to obtain deep imaging observations through the luminance broad-band and He II 468.6 nm, [O III] 500.7 nm, He I 587.5 nm, H, [N II] 658.4 nm,…
Discovery of a 25 parsec-long precessing jet emanating from the old nova GK Persei
Michael M. Shara, Kenneth M. Lanzetta, James T. Garland +6
Classical nova eruptions result from thermonuclear-powered runaways in, and ejection of, the hydrogen-rich envelopes of white dwarf stars accreted from their close binary companion…
Introducing the Condor Array Telescope: IV. A possible nova super-remnant surrounding the putative recurrent nova KT Eridani
Michael M. Shara, Kenneth M. Lanzetta, James T. Garland +10
Just 10 recurrent novae (RNe) - which erupt repeatedly on timescales shorter than one century - are known in our Galaxy. The most extreme RN known (located in the Andromeda galaxy)…
Introducing the Condor Array Telescope: III. The expansion and age of the shell of the dwarf nova Z Camelopardalis, and detection of a second, larger shell
Michael M. Shara, Kenneth M. Lanzetta, James T. Garland +7
The existence of a vast nova shell surrounding the prototypical dwarf nova Z Camelopardalis (Z Cam) proves that some old novae undergo metamorphosis to appear as dwarf novae thousa…
Introducing the Condor Array Telescope. II. Deep imaging observations of the edge-on spiral galaxy NGC 5907 and the NGC 5866 Group: yet another view of the iconic stellar stream
Kenneth M. Lanzetta, Stefan Gromoll, Michael M. Shara +6
We used the Condor Array Telescope to obtain deep imaging observations through the luminance filter of the entirety of the NGC 5866 Group, including a very extended region surround…
Catching VY Sculptoris in a low state
L. Schmidtobreick, E. Mason, S. B. Howell +4
Context. In the context of a large campaign to determine the system parameters of high mass transfer cataclysmic variables, we found VY Scl in a low state in 2008. Aims. Making use…
Infrared studies of Nova Scorpii 2014: an outburst in a symbiotic system sans an accompanying blast wave
Vishal Joshi, D. P. K. Banerjee, N M Ashok +2
Near-IR spectroscopy is presented for Nova Scorpii 2014. It is shown that the outburst occurred in a symbiotic binary system - an extremely rare configuration for a classical nova…
