[Abridged] Whether technological societies remain small and planet-bound like our own, or ultimately span across galaxies is an open question in the Search for Extraterrestrial Intelligence. Societies that engineer on a galactic scale are classified as Type III on Kardashev's scale. I argue that Type III societies can take the form of blackboxes, entire galaxies veiled in an opaque screen. A blackbox has a temperature that is just above that of the cosmic microwave background. The screen can be… 

There's No Place Like Home (in Our Own Solar System): Searching for ET Near White Dwarfs

The preponderance of white dwarfs in the Milky Way were formed from the remnants of stars of the same or somewhat higher mass as the Sun, i.e., from G-stars. We know that life can exist around

The Search for Extraterrestrial Intelligence (SETI) has so far come up negative for Kardashev Type III societies that capture all starlight from a galaxy. One possible reason is that shrouding a star

S1473550421000252jra 359..376

Interstellar travel in the Milky Way is commonly thought to be a long and dangerous enterprise, but are all galaxies so hazardous? I introduce the concept of galactic traversability to address this

Abstract Suppose that advanced civilizations, separated by a cosmological distance and time, wish to maximize their access to cosmic resources by rapidly expanding into the universe. How does the

OUR SKY NOW AND THEN: SEARCHES FOR LOST STARS AND IMPOSSIBLE EFFECTS AS PROBES OF ADVANCED EXTRATERRESTRIAL CIVILIZATIONS

Searches for extraterrestrial intelligence using large survey data often look for possible signatures of astroengineering. We propose searching for physically impossible effects caused by highly

The Breakthrough Listen Search for Intelligent Life: Target Selection of Nearby Stars and Galaxies

We present the target selection for the Breakthrough Listen search for extraterrestrial intelligence during the first year of observations at the Green Bank Telescope, Parkes Telescope, and Automated

A qualitative classification of extraterrestrial civilizations

TLDR
A basic taxonomic approach to ETCs is taken and the implications of the new classification on E TCs observational patterns are investigated, including the existence of a Kardashev Type III ETC in the Milky Way and the weakens the Fermi paradox.

The High Rate of the Boyajian's Star Anomaly as a Phenomenon

Boyajian's Star (KIC 8462852) undergoes mysterious, irregular eclipses that aren't yet explained. It also appears to have dimmed over a time of several years, possibly decades. I show that Kepler's

Abstract If advanced civilizations appear in the universe with an ability and desire to expand, the entire universe can become saturated with life on a short timescale, even if such expanders appear

THE Ĝ INFRARED SEARCH FOR EXTRATERRESTRIAL CIVILIZATIONS WITH LARGE ENERGY SUPPLIES. III. THE REDDEST EXTENDED SOURCES IN WISE

Nearby Type iii (galaxy-spanning) Kardashev supercivilizations would have high mid-infrared (MIR) luminosities. We have used the Wide-field Infrared Survey Explorer (WISE) to survey ∼ 1 × 10 5 ?>

Galactic-scale macro-engineering: looking for signs of other intelligent species, as an exercise in hope for our own

If we consider Big History as simply 'our' example of the process of cosmic evolution playing out, then we can seek to broaden our view of our possible fate as a species by asking questions about

EXTRAGALACTIC SETI: THE TULLY–FISHER RELATION AS A PROBE OF DYSONIAN ASTROENGINEERING IN DISK GALAXIES

If advanced extraterrestrial civilizations choose to construct vast numbers of Dyson spheres to harvest radiation energy, this could affect the characteristics of their host galaxies. Potential

A kiloparsec-scale hyper-starburst in a quasar host less than 1 gigayear after the Big Bang

TLDR
A spatially resolved image of [C ii] emission of the host galaxy of J114816.64+525150.3 that demonstrates that its star-forming gas is distributed over a radius of about 750 pc around the centre, comparable to the peak in Arp 220.

THE Ĝ INFRARED SEARCH FOR EXTRATERRESTRIAL CIVILIZATIONS WITH LARGE ENERGY SUPPLIES. II. FRAMEWORK, STRATEGY, AND FIRST RESULT

We describe the framework and strategy of the Ĝ infrared search for extraterrestrial civilizations with large energy supplies, which will use the wide-field infrared surveys of WISE and Spitzer to

Are Spiral Disks Really Opaque

We compare the ultra-violet, optical, and far-infrared emission for a sample of 135 spiral galaxies in order to address the widely debated problem concerning the opacity of spiral disks. We find that

THE Ĝ INFRARED SEARCH FOR EXTRATERRESTRIAL CIVILIZATIONS WITH LARGE ENERGY SUPPLIES. I. BACKGROUND AND JUSTIFICATION

TLDR
It is found that the maximum Galaxy colonization timescale is actually much shorter than previous work has found, and that many "sustainability" counter-arguments to Hart's thesis suffer from the monocultural fallacy.

TERRESTRIAL PLANETS ACROSS SPACE AND TIME

The study of cosmology, galaxy formation, and exoplanets has now advanced to a stage where a cosmic inventory of terrestrial planets (TPs) may be attempted. By coupling semianalytic models of galaxy

The Galactic Habitable Zone: Galactic Chemical Evolution

Abstract We propose the concept of a “Galactic Habitable Zone” (GHZ). Analogous to the Circumstellar Habitable Zone (CHZ), the GHZ is that region in the Milky Way where an Earth-like planet can
