    Authors: Alfredo B. Henriques and Luis E. Mendes
    Commets: 8 pages

    My horosho znaem fermionnye zvezdy - k nim otnosyatsya belye karliki, neitronnye i, poka gipoteticheskie, kvarkovye zvezdy. Bolee dvadcati let nazad byla razrabotana teoriya bozonnyh zvezd - sostoyashih iz tak i ne otkrytyh do segodnyashnego dnya skalyarnyh chastic. No okazyvaetsya est' i smeshannye bozonno-fermionnye konstrukcii, kotorye nastol'ko gibki, chto pozvolyayut s pomosh'yu odnoi modeli ob'yasnit' ogromny ryad yavlenii - ot ob'ektov s atomnymi razmerami i massoi 1018 g, do ob'ektov s galakticheskimi massami, v kotoryh nebol'shoe yadro okruzheno protyazhennoi obolochkoi.

    Na segodnya eta model' - skoree igra uma, no vdrug zavtra kto-to Obnaruzhit takuyu zvezdu (ili galaktiku:?)

    Commets: Ph.D. thesis, Caltech. 196(!) pages including low-resolution figures.

    Zhalko, chto u nas net nekoego edinogo saita, kuda mozhno bylo by vykladyvat' dissertacii. Nespecialistam budet interesno pochitat' vvedeniya k kazhdoi glave. Krome togo, na moi vzglyad, v dissertacii sobrana horoshaya bibliografiya.

    Tak kak eto dissertaciya i avtor ne byl ogranichen ob'emom, mnogie voprosy v nei rassmotreny ochen' podrobno. Vyvody dissertanta takovy:

    • Vysokotochnaya lokalizaciya dolgih vspleskov ukazyvaet na ih svyaz' s normal'nymi galaktikami s moshnym zvezdoobrazovaniem na umerennyh krasnyh smesheniyah poryadka edinicy.
    • Radial'noe raspredelenie mest vspyshek v galaktikah ne soglasuetsya s gipotezoi sliyaniya dvoinyh neitronnyh zvezd. No horosho korelliruet s ul'trafioletovym izlucheniem galaktik, chto ukazyvaet na vozmozhnuyu svyaz' s oblastyami obrazovaniya massivnyh zvezd.
    • Bolee chetko na svyaz' gamma-vspleskov so sverhnovymi ukazyvaet obnaruzhenie v opticheskih poslesvecheniyah GRB 980326 and GRB 011121 "plecha", otozhdestvlyaemogo s krivoi bleska sverhnovoi, nalozhivsheisya na zatuhayushee poslesvechenie. Drugoe ob'yasnenie proishozhdeniya etogo izbytka trebuet sushestvovaniya vokrug vspleska plotnoi obolochki, kotoruyu mog by sozdat' moshnyi zvezdnyi veter, chto opyat'-taki ukazyvaet na massivnye zvezdy.

    Vryad li vy naidete v etom manuskripte chto-to radikal'no novoe, no Koe-chto interesnoe v nem nesomnenno est'.

    Dlya ekonomii mesta v dissertacii privedeny risunki nizkogo razresheniya. Vysokokachestvennyi PDF-fail dissertacii mozhno vzyat' po adresu:

    astro-ph/0301135 Poisk kvazarov s z>5.7 v Sloan Digital Sky Survey: otkrytie eshe treh kvazarov s z>6 (A Survey of z>5.7 Quasars in the Sloan Digital Sky Survey II: Discovery of Three Additional Quasars at z>6)
    Authors: Xiaohui Fan et al.
    Commets: AJ in press (Apr 2003), 26 pages, 9 figures

    V obshem-to vse yasno iz nazvaniya. Pri obrabotke Sloanovskogo cifrovogo obzora neba naideny eshe tri kvazara s predel'nymi krasnymi smesheniyami: J114816.64+525150.3 (z=6.43), J104845.05+463718.3 (z=6.23) i J163033.90+401209.6 (z=6.05). Za podrobnostyami - v stat'yu.


    obzor astro-ph/0301143 Astronomiya neitrino vysokih energii (High-energy Neutrino Astronomy: Science and First Results)
    Authors: F. Halzen
    Commets: Latex2.09, uses crckapb.sty (included), 31 pages, 13 postscript figures placed with epsfig.sty. Talk presented at the 9th Course of Astrofundamental Physics, International School of Astrophysics D. Chalonge, Palermo, Sicily, Sept. 2002

    Obzor po sovremennoi astronomii neitrino vysokih energii s sootvetstvuyushim istoricheskim vvedeniem. Mnogo vnimaniya udelyaetsya sovremennym eksperimentam - AMANDA, DUMAND, IceCube. Obzor horosho proillyustrirovan, naprimer, tak vyglyadit spektr zhestogo fona fotonov na energiyah vyshe 1 GeV.

    astro-ph/0301145 Skorost' rasprostraneniya gravitacii i relyativistskaya zaderzhka vremeni (Propagation Speed of Gravity and the Relativistic Time Delay)
    Authors: Clifford M. Will
    Commets: 15 pages, 1 figure, to be submitted to the Astrophysical Journal

    Ochen' ostraya kriticheskaya stat'ya, opublikovannaya srazu posle press-konferencii Fomalona i Kopeikina na s'ezde Amerikanskogo Astronomicheskogo Obshestva (press konferenciya byla 7 yanvarya, a stat'ya vyshla uzhe 9-go).

    Avtor utverzhdaet, chto v provedennom eksperimente izmeryalas' ne skorost' rasprostraneniya gravitacii, a odin iz postn'yutonovskih parametrov, kotoryi izvesten s ochen' vysokoi tochnost'yu po ryadu eksperimentov (tipa lazernoi lokacii Luny) v Solnechnoi sisteme.

    Polovinu stat'i zanimayut slozhnye formuly, no vvedenie i zaklyuchenie prosto zahvatyvayushi.


    mikroobzor astro-ph/0301146 Geodezicheskaya precessiya v pul'sare PSR B1913+16 (Geodetic Precession in PSR B1913+16)
    Authors: M. Kramer (Manchester University, Jodrell Bank), O. Loehmer, A. Karastergiou (MPIfR Bonn)
    Commets: 4 pages,to appear in "Radio Pulsars" (ASP Conf. Ser.), eds. M. Bailes, D. Nice, & S. Thorsett

    V ochen' korotkoi stat'e sobrany sovremennye dannye po geodezicheskoi precessii neitronnoi zvezdy (precessii v iskrivlennom tyagoteniem prostranstve-vremeni) v Hals-Teilorovskom dvoinom pul'sare (eta sistema byla otkryta pervoi i nablyudaetsya dol'she vseh ostal'nyh).



    Poskol'ku k sozhaleniyu nikto ne vzyalsya za obzory razdela physics, my budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v etoi chasti Arhiva.


    physics/0301003 Geometry of Time and Dimensionality of Space
    Authors: Metod Saniga
    Commets: 10 pages, 4 figures, to appear in the proceedings of the NATO ARW "The Nature of Time: Geometry, Physics and Perception," edited by R. Buccheri, M. Saniga and W.M. Stuckey, Kluwer Academic Publishers, Dordrecht / Boston / London, 2003, pp. 131-143

    Na moi vzglyad - eto otlichnyi primer nauchnoi "al'ternativy". Obratite vnimanie, chto rabota podderzhana grantami ves'ma i ves'ma ser'eznyh organizacii. Tak chto "v ocherednoi raz nepravy" te, kto polagaet, chto sredi professional'nyh uchenyh sushestvuet zagovor protiv al'ternativnyh teorii.

    Mozhno sdelat' dva zamechaniya.
    1. Avtor v nekotorom smysle zakladyvaet to, chto hochet poluchit'.
    2. Pytayas' ob'yasnit' "netipichnye" dlya normal'noi fiziki yavleniya, avtor izbegaet (po krainei mere v etoi stat'e) ob'yasneniya standartnyh veshei.
    Odnako, stat'ya neprostaya (dlya nematematika), potomu, vozmozhno ya nedostatochno razobralsya i zamechaniya b'yut mimo celi (publikacii etogo avtora mozhno naiti na ego stranice: http://www.ta3.sk/~msaniga/).


    physics/0301010 Proposal of an experimental strategy to introduce relativity in elementary physics courses
    Authors: Roberto Assumpcao
    Commets: 7 pages,4 figures

    Kak "na pal'cah" izlagat' teoriyu otnositel'nosti? Delo neprostoe. Napomnim, chto u nas osnovy STO vhodili v normal'nyi shkol'nyi kurs fiziki. Odnako, po svoemu opytu mogu skazat': mne bylo neponyatno, kogda uchilsya, a kogda uchil - ne do vseh smog donesti.


    physics/0301012 A model of population dynamics - further investigations
    Authors: Iwona Mroz
    Commets: 17 pages, 6 figures

    Navernoe, mnogie chitali interesnye issledovaniya S. Kapicy po povodu dinamiki naseleniya Zemli i t.p. Esli chitali, i ponravilos', to prochtite i eto.


    physics/0301014 What causes a neuron to spike?
    Authors: Blaise Aguera y Arcas, Adrienne Fairhall
    Commets: 18 pages, 10 figures

    Po nazvaniyu mozhet pokazat'sya, chto stat'ya populyarnaya, no eto ne tak. Eto original'noe issledovanie.


    physics/0301015 Fuzzy Space Time, Quantum Geometry and Cosmology
