Distribution and motion of CO in M31 [PDF]
Symposium - International Astronomical Union, 1985 M31 is among the few galaxies whose solid angle is more than 100 times the beam area of currently operational millimeter-wave telescopes. Roughly 10% of its area has been mapped in the J=1→0 line of CO with the 7-m telescope at Bell Laboratories. The data lie on the major and minor axes and in a filled 20′ by 15′ field.

The Astrophysical Journal, 1992 We calculate the broad-band spectrum expected of a 10 exp 7 solar mass black hole accreting from an ambient galactic wind in the nucleus of M31, and we discuss several testable predictions of this model: (1) when resolved, this source will probably be elongated, perhaps in the direction of the semistellar nucleus BD +40 148 deg; (2) its radio spectral ...

Direct DEBs in M31 and M33 [PDF]
Highlights of Astronomy, 2004 The DIRECT project (as in “direct distances”) started in 1996 with the long-term goal of obtaining distances to two important galaxies in the cosmological distance ladder – M31 and M33 – using detached eclipsing binaries (DEBs) and Cepheids. These two nearby galaxies are the stepping stones in most of the current effort to understand the evolving ...

The Plant Genome, Volume 19, Issue 2, June 2026.Abstract A framework beyond single‐reference genomes is needed to understand transcription factor evolution. This study employed an integrated haplotype‑resolved genomes–transcriptome atlas–machine learning to characterize the transcription factors of autotetraploid green jujube (Ziziphus mauritiana).

HST Proper Motions of Andromeda V and Andromeda VI
The Astrophysical JournalWe measure the absolute proper motions of Andromeda V (And V) and Andromeda VI/Pegasus (And VI) dwarf galaxies, satellites of M31 located near its galactic plane.

The Astrophysical Journal Supplement Series, 2023 We introduce the New-ANGELS program, an XMM-Newton survey of a ∼7.2 deg ^2 area around M31, which aims to study the X-ray populations in the M31 disk and the X-ray-emitting hot gas in the inner halo of M31 up to 30 kpc. In this first paper, we report the

The Globular Cluster System of M31 [PDF]
Symposium - International Astronomical Union, 2002 This review presents the current status of our knowledge of M31 star clusters. Given the broadness of the subject, I chose to focus on some of its aspects which are not covered by the other participants in this conference.

Chandra Observations of M31 [PDF]
Symposium - International Astronomical Union, 2001 As part of the Chandra GTO program we are monitoring and surveying M31 using the HRC and ACIS cameras. These observations have resolved the nuclear X-ray source into five separate sources, one of which is very soft and may (or may not!) be associated with the central super-massive black hole.

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.Abstract In recent decades, tropical cyclone (TC) track forecasting has improved significantly. However, prediction of TC genesis (TCG) remains challenging. Accurate prediction of TCG is critical for disaster prevention and mitigation. This study develops an interpretable deep learning model that integrates 3D‐residual blocks with gated recurrent units

Destination recovery during COVID-19 in an emerging economy: Insights from Perú
European Research on Management and Business Economics, 2022 The onslaught of the COVID-19 pandemic has had a critical impact on the travel and tourism sector. Tourist destinations in developing countries are even more susceptible to negative trends of this sort due to the importance of tourism in emerging ...
